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>
