Answer:
0.67
Explanation:
In this population there are:
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 frequency of the A1 allele can be thus calculated using the following formula:
[tex]freq(A1)=\frac{2*A1A1\ + A1A2}{2*N} \\\\freq(A1)=\frac{2*104\ + 55}{2*196} \\\\\\freq(A1)= 0.67[/tex]
