A genetic counsellor is working with a couple who have just had a child who has a debilitating autosomal recessive form of a diseasetermed epidemolysis bullosa (which causes severe external and internal skin fragility resulting in blistering etc). Neither parent hasepidemolysis bullosa, nor does anyone in their families. What should the counsellor say to this couple?OA. "Because no one in either of your families has epidemolysis bullosa, you are not likely to have another baby with epidemolysisbullosa. You can safely have another child."OB. "Because you have had one child with epidemolysis bullosa, you must each carry the allele. Any child you have has a 50%chance of having the disease."OC. "Because you have had one child with epidemolysis bullosa, you musteach carry the allele. Any child you have has a 25% chance of having the disease."OD. "Because you have had one child with epidemolysis bullosa, you must both carry the allele. However, since the chance of havingan affected child is 25%, you may have more children without worrying about having another child with epidemolysis bullosa."OE. "You must both be tested to see who is a carrier of the epidemolysis bullosa allele."
