Factors Affecting Genetic Variation Answers

A population of snakes that eat small rodents enters a new habitat. In the new habitat, there are many species of rodents, and their populations are high because there are few natural predators. What will most likely be the effect on the genetic variation of the snake population?

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.Which change in the gene pool occurred in the greater prairie chicken population?

Genetic drift in a population affects the gene pool in which of the following ways?

In a population of seals, most of the seals have similar coloring. However, one seal has albinism. This seal is white and is almost completely blind. What is most likely the cause of this difference from the rest of the population?

In Wisconsin, a very large population of lake trout, in which individuals mate at random, experiences no migration, mutations, nor selective pressure for a number of years. Which of these is most likely to occur in the population?

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
