Albinism is an autosomal recessive condition. Which answer choice shows the genotypic ratio when an albino female mates with a male that is heterozygous for the albinism trait?
O AA: 2 Aa: 2 aa
1 AA: 2 Aa: 1 aa
2 AA: 2 Aa: O aa
2 AA: O Aa:2 aa

The correct answer is - O AA: 2 Aa: 2 aa

Explanation:

In the given question there is an albino mother (aa), and a heterozygous male or father (Aa) crossed to generate offspring, the genotypic ration in between by this cross would be :

Gametes:

Albino mother - a, a

heterozygous male - A and a

Cross:

        a      a

A     Aa     Aa

a       aa      aa

Thus there are 2 heterozygous and two albino and no true breeding dominant present thus, the correct answer would be - O AA: 2 Aa: 2 aa

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
