If both parents are homozygous for a recessive trait (aa), all of their children will inherit one recessive allele (a) from each parent. Therefore, all of their offspring will also be homozygous recessive (aa) and will express the trait.
As a result, the probability that they will have a child who does not have this trait in their phenotype is:
**0%**
So the correct answer is 0%.
