Answer 1

A

Step-by-step explanation:

Answer 2

To calculate the frequency of the 72 allele, you need to find the total number of alleles in the population and then determine how many of those alleles are the 72 allele.

Given the table, the number of individuals with each genotype is as follows:

- TITI: 50 individuals

- 7172: 60 individuals

- 1113: 40 individuals

- 7272: 50 individuals

- T2T3: 55 individuals

- T373: 45 individuals

To find the total number of alleles, sum up the counts of each genotype:

Total alleles = (2 alleles per individual) * (total number of individuals)

Total alleles = 2 * (50 + 60 + 40 + 50 + 55 + 45) = 2 * 300 = 600 alleles

Now, find the number of alleles that are the 72 allele:

Number of 72 alleles = Number of individuals with 72 allele * 2

Number of 72 alleles = 60 * 2 = 120 alleles

Finally, calculate the frequency of the 72 allele:

Frequency of 72 allele = (Number of 72 alleles / Total alleles) * 100

Frequency of 72 allele = (120 / 600) * 100 = 0.2 * 100 = 20%

So, the frequency of the 72 allele is 20%.
