Frequency of alleles within a population:

Dominant allele frequency + recessive allele frequency = 1

The equation is written as "p+q=1," where p is the frequency of the dominant allele, and q is the frequency of the recessive allele.

Frequencies are usually written in decimals.

Dominant allele frequency = 650/1000

= 0.65

Therefore, p= 0.65

p+q = 1

0.65+q = 1

Therefore, q is equal to 0.35,

In conclusion, the frequency of the dominant allele is 0.65, while the frequency of the recessive allele is 0.35.

First calculate the genotype frequencies via dividing variety of persons via inhabitants entire: AA: 1469/1612=.911 Aa: 138/1612=.086 aa: 5/1612=.003 Now calculate allele frequency: it quite is accomplished via taking the genotype frequency of the two homozygote and including it a million/2 the genotype frequency of the heterozygote. the explanation why is that the heterozygote has the two alleles. .911+ (.5(.086))=.954 is the frequency of A a million-.954=.046 is the frequency of a.
