A normal appearing couple is found to be heterozygous recessive for albinism. Both have the genotype Aa. The gene responsible for albinism is recessive to the normal pigment-producing gene. What are the chances of their children being albino?

To determine the probabilities that the child will have albinism, what you can do is simply find the probabilities of each parent providing the recessive allele for pigment production, which is 1/2.

Multiply them together to obtain the genotype of the child with albinism, so it would be 1/2 • 1/2 = 1/4.

The probability would be 25%.

Answer:

The probability is 25%

Explanation:

Mother: Aa

Father: Aa

Aa x Aa =  AA - Aa - aA - aa

The recessive homozygous aa is the one which produces albinism, so then, there are 4 possible genotypes andthe  only one that can produce albinism, gives us a probability of 25%
