PLEASE HELP ASAP WILL MARK BRAINLEST!!!!!!If both your mother and father have PKU disease, what is true? A. You will not have the disease because the dominant trait is expressed. B. Since PKU is a recessive disease, your chances of having it are 100% C. Since both parents are homozygous, your chances of having it are 50% D. There is a 75%chance that you will be a carrier of the disease, but you will not show symptoms.

Answer 1

Since PKU is a recessive disease, each parent's genes can be represented by pp. When you complete the Punnett square the results in each square are pp. So, since all of the square have pp, there's a 100% chance.
