There are three modes of natural selection: stabilizing selection, directional selection and diversifying/ disruptive selection. Describe each mode and explain how each mode affects the evolution of a population.

10. What is directional, stabilizing and disruptive selection and what roles do they play in adaptation and speciation?

10. What is directional, stabilizing and disruptive selection and what roles do they play in adaptation and speciation? 11. What is genetic drift? What role does it play in moving a population from one adaptive peak to a more fit adaptive peak?

We also talked about directional selection, disruptive selection, and balancing selection. Define these terms, and give an example of each. How are these types of selection similar, and how are they different? Are the traits under selection polygenic, or do they follow mendelian inheritance? What happens to the allelic and genotypic frequencies for each of these as they progress over time?

1. Note the primordial, primary, secondary and tertiary (Graafian) follicles. How do they differ from one another? What new structures are apparent as the follicles mature? What extant structures change during folliculogenesis? 2. The human uterus, unlike that of the mouse, has a unified structure (corpus). How does a bicornuate uterus serve the reproductive needs of the mouse (and why don’t humans have this type of uterine structure?
