Document Summary
First half key points mean to be alive. Cell theory and common ancestry hypothesis (null & alternative) and prediction experiment proving cell theory (spontaneous or not) exception to cell theory theory of evolution (darwin and wallace) - acts on populations. Natural selection (explains how evolution occurs) - 3 conditions (heritable, variation, fitness) - acts on individuals fitness. Artificial selection: how fast (environmental factors/number of genes, how far (deleterious trade-offs, available genetic variation) Hwe allele frequency genotype frequency phenotype frequency industrial melansim departure from expectations four factors affect af: ns, genetic drift, gene flow, mutation p^2 + 2pq +q^2 is true even if not in hw. If expected are similar to observed, can"t reject null hypothesis. Hla locus and immune function - if you are heterozygote probably stronger immune system - could increased heterozygosity impact mate choice heterozygote advantage (co dominance) whippo hypothesis cryptic species - dna barcoding - focus on one specific gene for species identification.
