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

wait any answer choices plz

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
