Answer to Question 1

ANS: B, D, E
Characteristics of autosomal recessive inheritance include males and females are equally affected, carrier parents have a 25 chance of producing an affected child, and carrier parents have a 50 chance of producing a carrier child in each pregnancy. Most affected persons who are males and all daughters of an affected male are carriers are characteristics of X-linked recessive inheritance.

Answer to Question 2

ANS: B, D, E
Specific risk factors that are indications for prenatal testing include inherited disorder, cytomegalovirus infection (teratogenic infection), and previous stillbirth or neonatal death. Previous twins or previous preterm birth are not specific risk factors that are indications for prenatal testing.
