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 […]

Alleles And Hardy Weinberg

This week we did lots of number crunching with calculating allele distribution in populations. Most of these where mock populations but we did talk about how sickle-cell anemia and malaria is related. The main concept is that if you are heterozygous for sickle-cell anemia you have an advantage when fighting off malaria, heteroygous simply means […]

Reflecting Upon Natural Selection

Having taken biology courses in the past I have a pretty strong understating of natural selection and how it works. The main conclusion that this week brought me too was that evolution can happen faster than one would think. Both the finches and the mice we heard about adapted in a very short amount of […]
