The allele frequency of black allele in the year2014 was 0.5 I.e.(100/200) whereas it remained only 0.3 in the year 2016.
The change in allele frequency suggests that yes there is evolution because the allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow which accounts for the driving forces of evolution.

a population of rock pocket mice were observed on a black substrate. the population contained individuals with both black and white fur. The black allele (B), is dominant over the white allele (b). A scientist in the field counts 640 black mice and 360 white mice out of 1000 total mice. She is interested in tracking evolution in the population. Please show your work for below questions. A)What is the frequency of the white allele? B)What is the frequency of...

RED EXTRA CREDIT EXERCISE: INTERACTION BETWEEN EVOLUTIONARY FORCES A species of mice inhabits a coastal plain of white sand (See Fig. 1). The most common fur color ispale gray, making up 85% of the population. The dominant allele for coat color is black, with the recessive allele coding for the pale gray phenotype. The mice mainly feed on seeds from the local Moave grass, but a few (10%) are also able to digest the young growing shoots of the local...

1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

Question1 2 pts A population of ferrets with a neutral allele F governing coat color. F shows incomplete dominance such that FF ferrets are black, Ff ferrets are grey, and ff ferrets are white. They migrate from the mainland, where the F allele is at an abundance of 50%, to three islands. These islands differ in size one small, one medium-sized, and one large. The larger islands can support more ferrets. A stable population of 50 ferrets lives on the...
In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive)....
In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...

2.3 Problem 3 The Hardy-Weinberg equation is useful for predicting the percent of a hu- man population that may be heterozygous carriers of recessive alleles for certain genetic diseases. Phenylketonuria (PKU) is a human metabolic dis- order that results in mental retardation if it is untreated in infancy. In the United States, one out of approximately 10.000 babies is born with the disor- der. Approximately what percent of the population are heterozygous carriers of the recessive PKU allele? If you...
