Imagine a genetic counselor working with a couple who have just had a child who is suffering from tay-sachs disease. neither parent has tay-sachs, nor does anyone in their families. which of the following statements should this counselor make to this couple? oa. "because no one in either of your families has tay-sachs, you are not likely to have another baby with tay-sachs. you can safely have another child." b. "because you have had one child with tay-sachs, you must each carry the allele. any child you have has a 50% chance of having the disease c. "because you have had one child with tay-sachs, you must each carry the allele. any child you have has a 25% chance of having the disease. d. "because you have had one child with tay-sachs, you must both carry the allele. however, since the chance of having an affected child is 25%, you may safely have three more children without worrying about having another child with tay-sachs."
