Galactosemia is a recessive human disease that is treatable by restricting lactose and glucose in the diet. Susan is heterozygous for this disease, while her partner Rick has galactosemia. Susan is pregnant with twins. If she has fraternal twins (non-identical) - what is the probability that one twin will be a girl with galactosemia and the other twin will be a boy without galactosemia? write your answer as a reduced fraction e.g. 1/16 If she has identical twins - - what is the probability that both of the twins will be girls who have galactosemia? write your answer as a reduced fraction e.g. 1/16
