Consider the genetic cross for absent-mindedness, which is a dominant trait. all of the offspring from this cross will be absent-minded. if two parents that are absent-minded have offspring that are not, what must be the genotypes of the parents?

Father: Dd
Mother: Dd

This is because when you cross these genetics in a punnet square, you get the possible outcomes of DD, Dd, Dd, dd. Therefore, there was a 25%chance of each offspring getting the gene, but each child did get the recessive trait.
