5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74 frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.873)
p² ≅ 0.02 q² ≅ 0.74 2pq ≅ 0.244)
q² = 0.13 p² = 0.4 2pq = 0.465) The dark-colored fur seems to have the greatest overall selective advantage
6) Dark lava changed the color of the substrate, from light to dark.
7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

The factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population. So, the correct option is A.
What do you mean by Mutation?The sudden, stable, and inheritable changes in the genetic material of an organism, are called mutations.
There are some assumptions of Hardy-Weinberg equilibrium. They are.
The population is large.The members of the population mate randomly with each other.No migration occurs between populations.No new mutations are favorable. No survival or reproductive advantage.Therefore, the factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population.

¿De qué manera pueden complementarse la
teoría Sintética y la teoría de los Equilibrios
Puntuados?
La teoría sintética
El redescubrimiento en 1900 de la teoría de la herencia de Mendel por el botánico y genetista holandés Hugo de Vries y otros llevó a un énfasis en el papel de la herencia en la evolución. De Vries propuso una nueva teoría de la evolución conocida como mutacionismo, que esencialmente eliminó la selección natural como un proceso evolutivo importante. Según de Vries (a quien se unieron otros genetistas como William Bateson en Inglaterra), en los organismos tienen lugar dos tipos de variación. Una es la variabilidad "ordinaria" observada entre los individuos de una especie, que no tiene consecuencias duraderas en la evolución porque, según de Vries, no podría "conducir a una transgresión de la frontera de la especie [es decir, al establecimiento de nuevas especies] incluso en las condiciones de la selección más rigurosa y continua ". El otro consiste en los cambios provocados por mutaciones, alteraciones espontáneas de genes que dan lugar a grandes modificaciones del organismo y dan lugar a nuevas especies: “La nueva especie se origina así de repente; es producido por el existente sin ninguna preparación visible y sin transición ”.
Muchos naturalistas se opusieron al mutacionismo y, en particular, los llamados biometristas, liderados por el estadístico inglés Karl Pearson, quien defendió la selección natural darwiniana como la principal causa de la evolución a través de los efectos acumulativos de variaciones individuales pequeñas y continuas (que los biometristas se supone que pasa de una generación a la siguiente sin estar limitado por las leyes de herencia de Mendel).

There are marked differences in the type of organisms found at four different locations at the same tidal height along ta rocky shore. What might account for this
Answer and Explanation:
Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.
Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.

Explanation:
When one glucose molecule travels through the glycolysis processes, four molecules of ATP are generated. Is it accurate to suggest that glycolysis produces two ATP molecules?
Answer:
No
Explanation:
Technically, this is inaccurate. To say that glycolysis produces two ATP molecules strays from the input of ATP needed. Overall, 4 ATP molecules are produced during glycolysis. However, there is an input of 2 ATP molecules at the beginning. Therefore, the correct statement would be that glycolysis produces 2 net ATP molecules, not that glycolysis produces 2 ATP molecules. (The word net makes a big difference!!).

Scientists observed that the populations of top-level consumers in a particular ecosystem were rapidly decreasing. Further studies revealed that there was also a decline in producer productivity. Which other changes did the scientists most likely observe in the ecosystem?
increased producer diversity
decreased population size at all levels
decreased primary consumer populations only
increased primary and secondary consumer diversity
Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F1 Generation 0 45 55 0 1
The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F2 Generation 23 31 22 24 0
Required:
a. Determine the genotypes of the original parents (P generation) and explain your reasoning.
b. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes.
Answer:
The genotypes of the original parents are
Male: X⁺Y Female: X⁻X⁻The Chi-square analysis leads us to accept the prediction of the parental genotypes.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
(a) The genotypes for the original parents (P generation) are
Male: X⁺Y
Female: X⁻X⁻
(b) The prediction of the parental genotype is accepted by the Chi-squared test analysis.
What is the eye color pattern in fruit flies?Drosophila Melanogaster is a fruit fly with abnormally big, brightly colored eyes.
The range in color from red to sepia to white reveals a lot about the genetic makeup of the fly.
(a) E = + ⇒ Dominant allele coding for wild-type eyes
e = - ⇒ Recessive allele coding for white eyes
Now, Crossing the : male wild-type with a female white-eyed
(Parental) = X⁺Y x X⁻X⁻
(Phenotype) = wild white
(Gametes) = X⁺ Y X⁻ X⁻
(Punnett square) = X⁺ Y
X⁻ = X⁺X⁻ X⁻Y
X⁻ = X⁺X⁻ X⁻Y
In (F1)generation = 2/4 = 1/2 = 50% of the progeny are expected to be wild-type females.
And 2/4 = 1/2 = 50% of the progeny are expected to be white-eyed males.
Thus, the percentages are almost 50:50, as the expected ones.
So, the genotypes of the original parents are
Male: X⁺Y
Female: X⁻X⁻
(b) Using Chi-squared test :
Observed fruit fly type:
Wild Type Male - 25
Wild Type Female - 31
White-eyed Male - 22
White-eyed Female - 24
Expected fruit fly type:
Wild Type Male - 25
Wild Type Female - 25
White-eyed Male - 25
White-eyed Female - 25
Now, chi square [tex]= \sum\dfrac{(O- E)^2 }{E}[/tex]
By putting numbers in the formula, we are getting
Wild Type Male - 0.16
Wild Type Female - 1.44
White-eyed Male - 0.36
White-eyed Female - 0.04
Now, X² = 0.16 + 1.44 + 0.36 + 0.04 = 2
Critical value = 7.82
X² (2) < critical value (7.82)
Thus, this is the evidence to accept the given hypothesis.

Fire and Mello conducted an experiment where they added no gene X RNA (b), anti-sense gene X RNA (c) or double stranded gene X RNA (d) to C. elegans embryos. They then did a hybridization experiment examining gene X mRNA levels in the embryo. Square (a) is a no probe control. How does this act as a control
Answer:
The correct answer is - It shows that an RNA probe is necessary to get a signal.
Explanation:
A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.
In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.
