A population is made up of individuals where 104 have the A1A1 genotype, 55 have the A1A2 genotype, and 37 have the A2A2 genotyp
Afina-wow [57]

Answer:

0.67

Explanation:

In this population there are:

  • 104 A1A1 individuals
  • 55 A1A2 individuals
  • 37 A2A2 individuals

N: 196

The frequency of the A1 is the amount of times that allele appears divided by the total number of alleles in the population.

  • The A1 allele is present twice in the A1A1 individuals and once in the A1A2.
  • Each individual has 2 alleles, so the total number of alleles is N × 2.

<u>The frequency of the A1 allele can be thus calculated using the following formula:</u>

freq(A1)=\frac{2*A1A1\ + A1A2}{2*N} \\\\freq(A1)=\frac{2*104\ + 55}{2*196} \\\\\\freq(A1)= 0.67
