A couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the woman’s family but not in the man’s family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?
