Question

Loss of habitat has decreased the population and number of alleles of Canadian lynx. A few survivors migrated to other forests and multiplied, but there is less genetic variation in the offspring. Which statement is true about this event?

A.
Genetic drift occurred in the population of Canadian lynx resulting in a founder effect later on.
B.
Gene flow occurred in the population of Canadian lynx. Then genetic drift occurred.
C.
The population of Canadian lynx experienced a founder effect. Later, genetic drift occurred.

Answer 1

Answer: A

Explanation: First habitat is lost that randomly thins the gene pool. This is genetic drift. Then later a new population is made from a small starting population which results in low genetic diversity. This is the founder effect.
