In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

A brown guinea pig mates with a white guinea pig. All of the babies have tan, or light brown fur. The hair color trait in guinea pigs is probably ____.
1. Sex linked
2. Recessive
3. Incomplete dominance
4. Codominant
Answer:
It would be sex linked.
Explanation:
As you know (if you do), when two animals mate, they combine their genes to make a baby. So of their skin colors are different like one is brown and one is white, then you get a baby that would look brownish white or have spots that are brown or white.

Explanation:
An estuary collects sediments from the ocean and rivers that feed into it. The sediments swirl around and then settle to form a mudflat. Eel grass is then established on the mudflat. The ecosystem changes over time and ultimately develops into a salt marsh that contains mangrove trees.

A)
The rotting remains of plants add to the fertility of the soil.
B)
The soil becomes so fertile that eel grass is replaced by other plant species.
C)

Answer:
Explanation:
Okay, so the female's eyes will be Xx because she carries it and I am not sure if the male is a carrier as well or not so if he is it will be Xx on the top and Xx on the side of the male is not then it will be XX and Xx and it does not matter which is on top which is on the bottom. If the male is a carrier then the outcomes will be XX, Xx, Xx, xx so they will have a 1:4 chance of getting white eyes if the male is NOT a carrier then it will be XX+Xx = XX, XX, Xx, Xx with no chances of having white eyes
The stages of mitosis were originally defined by cellular features observable through a light microscope.
a. True
b. False
Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

to produce
Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
The correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.
What is gene expression?It is the process by which cells produce protein from DNA molecules. DNA produces RNA which contains codes to produce amino acids.
The mRNA enters the ribosome which produced protein using the codons of mRNA.
Retroviruses have special machinery to produce the DNA from mRNA.
Therefore, the correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.

Explanation:
The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38
Answer:
The correct answer is - 1133.
Explanation:
According to H-W equilibrium;
p2 +2pq + q2 = 1 ........... eq.1 and
(p+q)2 = 1 ..............eq.2
Here q = frequency of the recessive allele,
and p = frequency of the dominant allele in the population
The genotype of p2 + 2pq shows the dominant(taster) phenotype.
The genotype of q2 shows the recessive(non-taster) phenotype.
q^2 = (2400 - 1482)/2400
= 0.3825
= 0.618
using eq. 2 we get p= 1-q
=0.382
2pq = No. of heterozygotes/2400
No. of heterozygotes = 1133.1648
5. What does EGS stand for in geothermal energy?
A) Engraved Geothermal System
B) Enhanced Geothermal System
C) Exhaust Gas System
D) Engineered Geophysical System
(EGS) stands Enhanced Geothermal Systems which can greatly increase geothermal energy utilization. Therefore, option (B) is correct.
What is EGS?Enhanced Geothermal Systems (EGS), which are also referred to as engineered geothermal systems on occasion, present a significant opportunity for significantly broadening the application of geothermal energy.
In an EGS, fluid is injected into the subsurface under conditions that are carefully regulated. This causes previously closed cracks to reopen, which in turn creates permeability in the rock. The increased permeability of the rock makes it possible for fluid to move freely within the newly fractured rock and for heat to be transported to the surface, where it can be used to create electricity.
