Which of the following situations could decrease the average fitness of a population? Snakes in a small, reproductively isolated populations must breed with blood- relatives. Atlantic salmons adapted to live in captivity escape from a fish farm and breed with wild stocks. All are correct Seeds dispersed by wind arrive on an island, germinate and begin breeding with the existing island population. A sudden forest fire kills 95% of a population of minks, leaving behind the remaining 5% to repopulate the area.

- Atlantic salmons adapted to live in captivity escape from a fish farm and breed with wild stocks: This situation could also decrease the average fitness of the population because the captive-bred salmon may not be adapted to survive in the wild, and their genes Show more…

Which of the following strategies would most rapidly increase the genetic diversity of a population in an extinction vortex? a. Establish a reserve that protects the population's habitat. b. Introduce new individuals transported from other populations of the same species. c. Sterilize the least fit individuals in the population. d. Control populations of the endangered population's predators and competitors.
