SUMMARY
The probability that the first child of a couple, both heterozygous for albinism (genotype Aa), will be albino (genotype aa) is 25%. This is derived from a Punnett square analysis of the genetic cross. Additionally, the probability that both of their first two children will be albino is calculated as 6.25%, which is the product of the individual probabilities for each child being albino (0.25 * 0.25).
