In case 2, we have a paternity problem, as the parents are recessive (aa) and the children are dominant (AA).
<h3>DOMINANCE AND RECCESSIVITY</h3>
An inheritance is said to be recessive when a certain trait is only expressed in zygosity, that is, an allele alone is not capable of manifesting a certain trait. We say that an inheritance is dominant when only one of the alleles is sufficient to manifest that trait. This means that this allele is expressed when it is zygous or heterozygous.
In this question, a verification method was requested to determine if the disease, however, exists a paternity error, this genealogy is not possible.
