D) is interested in the range of outcomes associated with different genotypes.

Question 13

Why are relatively few inherited disorders caused by dominant alleles?

Accepted Answer

A) Most disorders caused by dominant alleles lead to sterility,which means the dominant allele will not be passed on. 
B) Genetic testing can more readily identify dominant rather than recessive alleles;genetic counselling has more successfully reduced the incidence of disorders caused by dominant alleles. 
C) Every person with one of the dominant alleles will have the disorder,and people with most of these disorders do not usually live long enough to reproduce,so the allele will not be passed on. 
D) Individuals carrying dominant alleles for a disorder are less likely to actually have the disorder than are individuals carrying a recessive allele for a disorder.

Accepted Answer

A) are not serious enough to cause concern. 
B) can be minimized by using both kinds of studies to see if they yield similar results.
