How Selective Events Effect Populations

This week we did more work with genetics and how alleles are expected to flow when populations are under certain influences. For instance we did a lab where pairs where randomly made and the effects ranged from homologous recessive dying 100% of the time, to homologous recessive having a 50/50 chance of survival. This resulted in data that varies from the Hardy Weinberg equilibrium, and lets us see how these outside forces change allele distribution. This lesson from Khan Academy helps make understanding of ideas such as populations and natural section much easier: https://www.khanacademy.org/science/biology/her/heredity-and-genetics/a/natural-selection-in-populations. Another thing we did this week was plant some seeds that are meant to grow very quickly and there meant to have sprouted by Monday.
