Question

). You are studying an allele T that governs parasite resistance in a large population of gazelles. You observe that different combinations of T and t produce phenotypes that have different fitnesses due to differences in parasite resistance. The fitness of TT is 0.30, the fitness of Tt is 0.32, while the fitness of tt is 0.34. The T allele starts at a frequency of 0.70, while t starts at a frequency of 0.3. i. Assuming Hardy-Weinberg equilibrium except for selection, what will the frequency of T be in the next generation

Answer 1

The New Allelic frequency of the T allele in the next generation is 0.6865

Step-by-step explanation:

In the attached file you will find the resolved problem.

You will probably need the definitions of the following terms:

• Initial allelic frequency: (number of homozygote individuals + half number of heterozygote individuals) / Total number of individuals

• Relative contribution of each genotype: Zygote frequency x Relative aptitude

• Average aptitude W: It is the sum of relative contribution of each genotype to the next generation.

WTT x p2 + WTt x 2 x p x q + Wtt x q2

• Population Genotype frequency: Relative contribution of each genotype / Average aptitude

• Allelic frequency: Homozygote population genotype frequency + half heterozygote population genotype frequency
