Consider a particular hypothetical case in which the Baysian probability that an unaffected parent is heterozygous for a particular recessive allele is 20% and the other parent has the recessive condition; what is the chance that their first child would have the condition?

Given that one parent is heterozygous (with a 20% probability) and the other parent has the recessive condition (homozygous recessive), the chance of their child inheriting the condition depends on the heterozygous parent passing on the recessive allele. Since the heterozygous parent has a 50% chance of passing on the recessive allele, and this event has a 20% probability of being the case, the overall chance is 50% of 20%, which is 10%.
