Section 9.1: Mechanisms of Evolution and Effect on Populations

Section 9.1: Mechanisms of Evolution and Effect on Populations. SBI3U1. Evolution of the population. Although individual organisms with a selective advantage survive and reproduce, it is the populations that evolves not the individual organism.

Evolution in populations

Evolution in populations. Think Change over loooong periods of time. Gene pool: all the genes in a population. Not just the genes, but the variation of genes Allelic frequency; distribution of alleles. A population whose allelic frequency is not changing is in genetic equilibrium

Hardy-Weinberg p 2 + 2pq +q 2 = 1

Hardy-Weinberg p 2 + 2pq +q 2 = 1 1. A recessive condition occurs in one in every 20000 of a population. What percentage of the population are carriers of the condition?
