It is created by the direct action of natural selection.

It arises in response to changes in the environment

It must be present in a population before natural selection can act upon the population.

It tends to be reduced by the processes involved when diploid organisms produce gametes.

A population that has a higher average heterozygosity has less genetic variation than one with a lower average

Sample Question
A 25-year-old female comes to your OB/GYN practice at a highly respected medical center noted for it’s involvement in sequencing the human genome. Her primary complaint is amenorrhea. Since you have a keen interest in genetic bases for reproductive dysfunction, you obtain tissue from this young female and have the laboratory perform a gene scan. The result of this genetic analysis reveals a point mutation in the gene encoding for protein kinase A in theca and granulosa cells. Based upon these findings, what is an appropriate finding associated with her amenorrhea?

Over-expression of luteinizing hormone (LH) and follicle stimulating hormone (FSH).

Under-expression of gonadotropin releasing hormone (GnRH) by the paraventricular nucleus of the hypothalamus.
