A 47-year-old woman has developed osteoarthritis, hypertension, and breast cancer. Her mother also suffered from the same conditions at 51 years of age. The nurse explains that this could be a result of:

A) X-linked inheritance
B) Autosomal recessive inheritance
C) Autosomal dominant inheritance
D) Multifactorial inheritance


Ans: D
Feedback: X-linked conditions may be inherited in recessive or dominant patterns. Autosomal recessive conditions have a pattern that is more horizontal than vertical; relatives of a single generation tend to have the condition. Many birth defects and common health conditions such as heart disease, high blood pressure, cancer, osteoarthritis, and diabetes occur as a result of interactions of multiple gene mutations and environmental influences.
