Textbook Question
Chapter 19.6, Problem 2TYK
Populations that experience inbreeding may also experience
- a decrease in fitness due to an increased frequency of recessive genetic diseases.
- an increase in fitness due to increases in heterozygosity.
- very little genetic drift.
- no apparent change.
- increased mutation rates.
