Estimates of spontaneous mutation rates are made using dominant disorders because
A) it takes several generations for the phenotype to change.
B) they do not affect offspring.
C) the mutant phenotype is obvious.
D) they can be identified by DNA sequencing.
E) they are much more common than recessive disorders.

Question

Quizplus · Accepted Answer

Dominant disorders produce an obvious mutant phenotype, which makes it easier to identify and track mutations. This allows for more accurate estimation of spontaneous mutation rates.
