A hypothetical population of 500 cats has two alleles, T and t, for a gene that codes for tail length. The table below presents the phenotype of cats with each possible genotype, as well as the number of individuals in the population with each genotype. Assume that this population is in Hardy-Weinberg equilibrium.
1. What is the frequency of cats with long tails in the population? .84
2. What is the frequency of cats with short tails in the population? .16
3. What is the frequency of cats that are homozygous dominant in the population? .36
4. What is the frequency of the T allele in the gene pool of this population? .60
5. What is the frequency of the t allele in the gene pool of this population? .40
6. Use the Hardy-Weinburg equation to predict the frequency of heterozygous cats in the next generation. 0.48
7. Use the Hardy-Weinburg equation to predict the frequency of homozygous recessive cats in the next generation. 0.16
8. Use the Hardy-Weinburg equation and your answer to question 7 to estimate the frequency of the next generation. 0.40
This equation is just to show a bunch of different ratios between different phenotypes. If you can do the math it makes it really easy. Just know that whatever ratio the phenotypes have it will be the same as its offspring. Forget the youtube video it is not that complicated.
