A nurse educator is teaching a group of student nurses regarding problems of infertility and genetic inheritance of disease. Which statement made by the nurse indicates that teaching has been effective?
A) "A person's genotype is the observable expression of the traits."
B) "The total genetic makeup of an individual is referred to as the phenotype."
C) "In an autosomal recessive inherited disorder, the individual must have two abnormal genes to be affected."
D) "An individual is said to have an autosomal dominant inherited disorder if the disease trait is homozygous."
Answer: C
In an autosomal recessive inherited disorder, the individual must have two abnormal genes to be affected. A person's phenotype is the observable expression of traits, and the total genetic makeup of an individual is referred to as genotype. An individual is said to have an autosomal dominant inherited disorder if the disease trait is heterozygous-that is, the abnormal gene overshadows the normal gene of the pair to produce the trait.
