Human albinism is an autosomal recessive trait. Suppose that you find a village in the Andes where 1/4 of the population is albi
Aleks04 [339]

Answer:

500

Explanation:

According to the given information, the total number of albino people in the population= 1000/4 = 250.

Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.

The frequency of recessive allele (q) = square root of 0.25 = 0.5

Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5

Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%

Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
