The probability of the offspring of C&G to have zero AT alleles depends on if her husband G has AT alleles or not.
The principle of inheritance suggests that characters are randomly inherited by offspring from parents and that the dominant trait always appear in the offspring when present.
Genes contains the information for making the proteins for any trait.
Genes exists in alternative forms know as alleles.
If Celeste has zero AT alleles, the probability of her offspring to have AT alleles depends on if her husband G has AT alleles as well.
If G has zero AT alleles, the probability of C&G having a child that has zero AT alleles is 1.
However, the probability reduces if G has any AT alleles at all.
