A woman carries two alleles for an autosomal dominant genetic condition. Her husband does not possess the allele. What are the chances that their offspring would inherit the condition?

Answer 1

There is a 50% chance that their offspring will inherit the condition. Since the woman carries two alleles for the dominant genetic condition, she will pass on at least one of those alleles to her offspring. Since the condition is dominant, if the offspring inherits at least one copy of the allele, they will display the trait. The husband does not possess the allele, so it is not possible for the offspring to inherit the condition from him. Therefore, the chances of their offspring inheriting the condition would be 50%.
