A gene or trait that appears or expresses itself over a recessive trait is called
Answer:
it is called a dominant gene
Answer:
Its called a dominant gene.
Explanation:
"A dominant gene, or a dominant version of a gene, is a particular variant of a gene, which for a variety of reasons, expresses itself more strongly all by itself than any other version of the gene which the person is carrying, and, in this case, the recessive."

Which of the following is an example of gene flow?
O The movement of people on Earth steadily increases and alters the course of human evolution
An earthquake results in the formation of a canyon, splitting a population of toads apart
O A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest
A small population of grasshoppers gets blown away and isolated during a storm. The gene pool of the new population is different from the original population
An example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.
What is Gene Flow?Gene flow, which can also be referred to as gene migration, is the transfer of genes or genetic material from one population of a species to another.
Migration of humans from one region to another leads to people of one race intermarrying with people of another entire race.
For example, A European migrating to North America, and getting married to a North American thereby giving birth to offspring exhibiting traits of booth a European and a North American. A gene flow has occurred.Therefore, an example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.

What is one of the results of an increase in the amount of greenhouse gases in the atmosphere?
А
increased overall ocean salinity
B
decreased global polar ice melting
с
increased overall atmospheric humidity
D
decreased global surface temperatures
Answer:
C) Increased overall atmospheric humidityIncreasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.
What are greenhouse gases?The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.
Due to minute concentrations of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect.
Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

I WILL MARK YOU BRAINLYSSSSS
You are working with a population of snails. During the mating season, you observe that individuals in the population will only mate with others of the same genotype. For example, Mm individuals will only mate with Mm individuals, and mm individuals will only mate with other mm individuals. There are only two alleles for this gene (M is dominant; m is recessive). You have determined that the frequency of the M allele is 0.5. After one generation, what is the expected genotype frequency for Mm individuals in this population
If matings are not random in a population and individuals mate with other individuals of similar genotype/phenotype, h0m0zyg0us frequencies increase. In this example, the genotype frequency for Mm is F(Mm) = 0.25.
---------------------------------
In the exposed example, one of the assumptions of Hardy-Weinberg equilibrium is not accomplished. There are non random matings.
Individuals mate with other snails of the same genotypes
MM x MM
Mm x Mm
mm x mm
We can assume this is an example of matings by similar phenotypes.
Eventually, this mating system leads to an increase in the h0m0zyg0us genotype frequency, at the expense of heter0zyg0us ones in loci that determine the trait.
Allelic frequencies do not change. Only genotypic frequencies do.
This mating system tends to separate the population into two subgroups, decreasing the amount of heter0zyg0us individuals.
Matings Progeny
MM x MM 4/4 MMMM x Mm 1/4 MM + 2/4 Mm + 1/4 mmmm x mm 4/4 mmZygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(Mm) = 1/2 MmF(mm) = 4/4 mm + 1/4 MmSo, in the exposed example we know that the frequency of the dominant allele M is 0.5
f(M) = p = 0.5
knowing that p + q = 1, we can clear the equation to get the frequency of the recessive allele.
p + q = 1
0.5 + q = 1
q = 1 - 0.5
q = 0.5
f(m) = q = 0.5
Zygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(MM) = p² + 1/4 (2pq)
F (MM) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(MM) = 0.375
F(Mm) = 1/2 MmF(Mm) = 1/2 (2pq)
F(Mm) = 1/2 (0.5)
F (Mm) = 0.25
F(mm) = 4/4 mm + 1/4 MmF(mm) = q² + 1/4 (2pq)
F(mm) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(mm) = 0.375
The expected genotype frequency for Mm individuals in this population is F(Mm) = 0.25.
