Question

Natural selection acts upon ____________________________, evolution upon _______________________________.
What is the gene pool and how does natural selection act upon it?
If a version of a gene confers an advantage to survival and reproduction, that version of the gene will be favored by natural selection and we can expect the frequency of that gene to ______________________ within the population over time.
Versions of the gene that do not confer an advantage (or confer a disadvantage) should become _______________ prevalent .
This generation to generation change in the gene pool is called ________________________.
Changes to the genetic makeup of a population and the individuals within it can arise via two mechanisms. List and describe both. Both of these processes are ________________________________.
Once created, new combinations of genes will be acted upon by _________new alleles_______________________.
How is Darwinian “fitness” different than the typical definition used in common speech?
Natural selection is the primary driving force of evolution, but there are other mechanisms at play as well. Define the following means and explain how they contribute to the process of evolution.
1. Genetic drift
2. Bottleneck and founder effects (special types of genetic drift)
3. Gene flow
4. Sexual selection (a special type of natural selection)
