Tay-Sachs is a recessive disease that causes nerve cells to malfunction and results in death by age 4. Two healthy parents know from blood tests that each parent carries a recessive allele responsible for Tay-Sachs. If their first 3 children have the disease what is the probability that their 4th will have the disease? Show the Punnett square.
