Galactosemia is an autosomal recessive human disease that is treatable by restricting lactose and glucose in the diet. If two individuals who are both heterozygous for the recessive galactosemia allele have three children, what is the probability that two of the children will have galactosemia and one will not? Type your answer as a fraction (not a decimal), with no spaces (e.g. 1/16).
