Question

A hypothetical population of 200 cats has twoalleles, TL and TS, for alocus that codes for tail length. The table below describes thephenotypes of cats with each possible genotype, as well as thenumber of individuals in the population with each genotype. Whichstatements about the population are true?

Genotype Phenotype
(tail length) Number of individuals
in population
TLTL long

60
TLTS medium

40
TSTS short

100



Select all that apply.

1. Assumingrandom mating, each gamete has a 40% chance of having aTL allele and a 60% chance of having aTS allele.
2. Assumingrandom mating, each gamete has a 50% chance of having aTL allele and a 50% chance of having aTS allele.
3.Homozygotesmake up 30% of the population.
5. In theentire cat population, 60% of the alleles areTS.
6. In theentire cat population, the frequency of the TSallele is 0.5.
7. In theentire cat population, the frequency of the TLallele is 0.4.
8. In theentire cat population, 50% of the alleles areTS.
9.Heterozygotes make up 20% of thepopulation.
10. Heterozygotes make up 70% of thepopulation.
11. Homozygotesmake up 80% of the population.

Explanation / Answer

P2 =.4X.4=.16 Q2=.6X.6=.36 =.52X100=52% ========================================== TLTS=2PQ=.2X100=20% =========================== Select all that apply. Assuming random mating, each gamete has a 40% chance ofhaving a TL allele and a 60%chance of having a TSallele. In the entire cat population, 60% of the allelesare TS. In the entire catpopulation, the frequency of the TL allele is0.4. Heterozygotes make up 20% of the population.
