22. Evolution of Populations
Non-Random Mating
Multiple Choice
Multiple ChoiceIn a 2019 paper in Mammalian Genome, Chu et al. showed that golden retrievers with higher rates of inbreeding had fewer offspring, suggesting inbreeding depression. Which of the following conclusions could you draw about the population?
A
Lack of gene flow between dog breeds is responsible for the fewer offspring.
B
The small population size of golden retrievers has led to high rates of genetic drift in the breed.
C
Those golden retrievers with fewer offspring likely have decreased fitness due to excess homozygosity.
D
Natural selection is not occurring in golden retrievers.
