Question
Transcribed Image Text:A hypothetical population has two alleles for an "T" gene: T and t. In a random sample of 50 diploid zygotes (for a total of
alleles), the following genotypes were found: 15 TT, 25 Tt, and 10 tt.
Let's say that natural selection acts against the t allele in the initial population sampled above, and all 10 individuals with
tt genotype die off (leaving 0 tt individuals) and 10 of the individuals with Tt genotype die off (leaving 15 Tt individuals)
before reaching maturity. (The number of surviving adults in the population is 30).
What is the new frequency of the recessive allele after selection occurred?
O A. 0.25
O B. 0.75
O C.0.10
O D.0.50
Expert Solution
Step 1
An allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population.
