Document Summary

In 1837 darwin"s notes rst mentioned that species resemble each other because of sharing a common ancestor, not a common environment (di ers form lamarkism) In 1838 darwin read an essay on the principal of evolution by malthus which brought him to nally formulate his thoughts on natural selection. P = percent of dominant alleles q = percent of recessive alleles p + q = 1. P^2 is the probability of getting 2 dominant alleles q^2 is the probability of getting 2 recessive alleles. Assortative mating when paired with ns can lead to an increase in homozygosity and loss of genetic variability because of phenomena of endogamic depression since the harmful alleles will express themselves, and ns will purge the population. There are no other processes which a ects the allelic frequencies at a particular locus, genetic drift will eventually result inn the xation of an allele and the elimination of all others for a locus.
