Choose all the answers that apply. a population of rabbits is 60 percent gray and 40 percent white. an earthquake kills half of the white rabbits. what does this mean? 1. this is an example of gene flow. 2. this is an example of genetic drift. 3. this decreases the genetic diversity of the rabbit population. 4. this means the number of gray rabbits will increase over time.

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error) gene flow is an important mechanism for transferring genetic diversity among populations. The numbers of g ray rabbits does not increase so that would be eliminated and so as genetic drift is eliminated. The two answers are 1. This is an example of gene flow and 3. This decreases the genetic diversity of the rabbit population. Hope this helps.

The answer is 4 (the number of gray rabbits will increase over time

            Gland which regulate the function of other glands in the endocrine system is known as pituitary gland. It is also called as master gland, because it consists of anterior and posterior pituitary that secrete a variety of hormones and regulate the secretion of many other glands in the body.
