In a population, 25% of individuals exhibit albinism which is a lack of production of the pigment melanin. It is caused by two recessive allele (q2). What is the frequency of the recessive allele (g) in this population?

According to Hardy Wienberg's equilibrium, any population which faces not internal or external factors of change in allele frequency, the frequency of homozygous and heterozygous individuals will add up to be 1 and the frequency of dominant and recessive alleles will add up to be 1 in every generation. Where p is the frequency of dominant allele, q is the frequency of recessive allele, p2 is the frequency of homozygous dominant individuals, q2 is the frequency of recessive allele and 2pq is the frequency of heterozygous individuals.

p2 + 2pq + q2 = 1

Here,

q2 = 25/100 =0.25

q= = = 0.5

So, the frequency of the recessive allele will be 0.5

KINDLY RATE IF THIS WAS HELPFUL.
