Question

Part a - analyzing the gene pool of a hypothetical population a hypothetical population of 200 cats has two alleles, tl and ts, for a locus that codes for tail length. the table below describes the phenotypes of cats with each possible genotype, as well as the number of individuals in the population with each genotype. which statements about the population are true?

Answer 1

Heterozygotes make up 20% of the population.Homozygotes make up 80% of the population.In the entire cat population, 60% of the alleles are TS.In the entire cat population, the frequency of the TL allele is 0.4.Assuming random mating, each gamete has a 40% chance of having a TL allele and a 60% chance of having a TS allele.
The gene pool for tail length in the population is composed of alleles TL and Alleles TS .The allele frequency of TL is 0.4 (160/400). Another way to express this is that 40% of the alleles are TL .The allele frequency of Ts is 0.6 (240/400). Another way to express this is that 60% of the alleles are Ts .Therefore, each of the gamete either the sperm or the egg has a 40% chance of carrying allele TL and a 60% chance of carrying allele Ts, assuming mating is random.
