Quizplus · Accepted Answer

If both parents are carriers of a recessive trait, each parent has a 50% chance of passing on the recessive allele to their offspring. If both parents pass on the recessive allele, the child will be affected by the trait. Therefore, there is a 25% (or 1 in 4) chance of having an affected child.
