Question

As part of an orientation to a genetic counseling practice, a group of medical students is differentiating between autosomal recessive disorders and autosomal dominant disorders. Which of the following statements is true of autosomal recessive disorders?
a. They tend to have a more uniform symptomatology than autosomal dominant disorders.
b. They can manifest when present in one or both gene pairs

Answer 1

Answer: The answer is B- They tend to have more uniform symptomatology than autosomal dominant disorders

Explanation:

Autosomal recessive disorder is a disorder in which two copies of an abnormal gene is present in order for a disease or trait to develop. A person with this disorder inherits one gene alteration from each parent

However in autosomal dominant disorder one mutated copy of gene in each cell is sufficient enough for the trait to develop.

Autosomal recessive disorder is also inherited when symptomatology is more uniform than autosomal dominant
