Why do mutations appear more often with selective breeding?
A - They are selected for a desirable trait
B - Genetic diversity is increased
C - Desirable traits are only beneficial if mutations occur too
D - Genetic diversity is decreased
E - They will eventually disappear over time so they are not a problem
Answer: D - Genetic diversity is decreased
Genetic diversity is greatly decreased through the inbreeding process (breeding of closing related species) which mutations that are normally selected against will be selected.
