1. Scientists studied a population of 300 wolves over the course of multiple years. In their research, they were able to sequence the genotypes of those wolves and found that:
- 157 wolves were homozygous dominant for their coat color (CC)
- 113 were heterozygous (Cc)
- 30 were homozygous recessive (cc)

What is the genotypic frequency of the homozygous recessive genotype?

A. 10%
B. 100%
C. 37.7%
D. 52.3%
E. 28.8%

2. Scientists studied the same population of 300 wolves. What is the allele frequency for the recessive allele?

A. 50%
B. 28.8%
C. 5%
D. 23.8%
E. 57.7%
F. 10%

3. As the wolf scientists moved on to study a new population, they had only their understanding of the inheritance of coat color (and their calculators) with them as they tried to determine both genotypic and allele frequencies of this new population. They understood that the darker coat color was dominant (C) to the lighter gray coat (c). They observed, in this population of 52 wolves, that 10 had a light gray coat.

What is the frequency of heterozygotes in this population?

A. 49.2%
B. 19.2%
C. 43.9%
D. 56.1%
E. 31.5%

4. What is the frequency of homozygous dominant wolves in this population of 52 wolves?

A. 43.9%
B. 19.2%
C. 56.1%
D. 31.5%
E. 49.2%

Answer :

Among 300 wolves, genotypic frequency of homozygous recessive genotype is 10%, and allele frequency for recessive allele is 5%. Among 52 wolves, frequency of heterozygotes is 80.8%, and frequency of homozygous dominant wolves is 43.9%.


To find the genotypic frequency of the homozygous recessive genotype, we need to divide the number of homozygous recessive wolves (30) by the total number of wolves (300) and multiply by 100. So, the genotypic frequency of the homozygous recessive genotype is (30/300) * 100 = 10%.

To find the allele frequency for the recessive allele, we need to consider the fact that the homozygous recessive genotype (cc) only has one recessive allele (c). The total number of alleles in the population is twice the number of wolves (2 * 300 = 600). So, the allele frequency for the recessive allele is (30/600) * 100 = 5%.

In the new population of 52 wolves, if 10 have a light gray coat (homozygous recessive), then the frequency of homozygous recessive wolves is (10/52) * 100 = 19.2%.

To find the frequency of heterozygotes in this population, we need to subtract the frequency of homozygous dominant and homozygous recessive wolves from 100%. So, the frequency of heterozygotes is 100% - 19.2% (homozygous recessive) - frequency of homozygous dominant wolves (which we need to calculate) = 80.8%.

To find the frequency of homozygous dominant wolves in this population, we need to subtract the frequency of homozygous recessive and heterozygotes from 100%. So, the frequency of homozygous dominant wolves is 100% - 19.2% (homozygous recessive) - 80.8% (heterozygotes) = 43.9%.

The genotypic frequency of the homozygous recessive genotype is 10%, and the allele frequency for the recessive allele is 5%. In the new population of 52 wolves, the frequency of heterozygotes is 80.8%, and the frequency of homozygous dominant wolves is 43.9%.

In the first population of 300 wolves, the genotypic frequency of the homozygous recessive genotype is 10%, and the allele frequency for the recessive allele is 5%. In the second population of 52 wolves, the frequency of heterozygotes is 80.8%, and the frequency of homozygous dominant wolves is 43.9%.
