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

sesenic [268]
The species was a keystone species.

Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
