Document Summary
Sickle cell disease and parasite that causes malaria. Hardy- weinberg - how alleles change and the impact of evolution. Interbreeding group that share the same gene pool. Assume no flow of alleles in or out of the population. Inside is the two alleles they posess (genotype) The gene pool ignores the individual organism, just focuses on the alleles. Identify the frequency of each allele in the gene pool. Change in the frequency of alleles due to different parameters. Gene pools change if new alleles are created by mutations. Or, if alleles are introduced or removed from the pop. Will persist if beneficial or harmful, will not persist. An increase in allele frequency in some pops, or higher frequency. An increase in allele frequency in some pops, or higher frequency of sickle. Assume that the sickle allele had an advantage - survived longer and reproduced more. Temperature and access to nutrients was considered in different parasites.
