Exercise 1
Charles Darwin proposed DESCENT WITH MODIFICATION by means of natural selectionto explain modern and fossil biodiversityGenetic Variation:
Darwin’s theory of evolution by natural selection is heritable, or genetic variationHeritable traits are like eye color, hair color; and acquired traits are like work ethic, or how you fold your clothes
5 assumptions made in the Hardy-Weinberg Equilibrium Model
1.Large population size– so no random events do not change allele frequency
2.No immigration or emigration– no transport of allele in or out of population
3.No genetic variation– mutations could add new alleles and disrupt equilibrium
4.Random mating– population must have an equal probability of mating
5.No natural selection– all phenotypes must have equal reproductive success Allele frequencies
