a high population of greater prairie chickens once inhabited the prairies of illinois. the conversion of the prairies into agricultural land caused the chickens to lose their habitat. studies have concluded that this change greatly reduced the greater prairie chicken population. the habitat loss also resulted in a decrease in the population’s genetic variation.\nwhich change in the gene pool occurred in the greater prairie chicken population?\n○ gene mutation\n○ gene flow\n○ genetic drift\n○ genetic resistance

Answer

Brief Explanations:

Genetic drift occurs when a population size is greatly reduced, like the greater prairie - chicken population due to habitat loss. This can lead to a decrease in genetic variation. Gene mutation is a change in DNA sequence, gene flow is the transfer of genes between populations, and genetic resistance is related to an organism's ability to withstand something like a disease or toxin. None of these other concepts fit the described situation as well as genetic drift.

Answer:

genetic drift
