Document Summary
Gene pool: all genetic info in a breeding population. Reproductive isolation: mechanism that prevents two populations from interbreeding. Our ability to see processes like natural selection. Large scale change over long stretches of time. Null hypothesis p + q = 1 p^2 + 2pq + q^2=1. Start with recessive, it will give u q2 (q divided by pop. ) When u know two percentages, look at recessive to calculate q2, use that to understand what q is and what p is. Heterochromia: results in pop where genetic diversity has gone down (two eye colors) Dna sequence codes for array of amino acids-> makes proteins. Amino sequence might change-> change to the protein. Transposable elements: copying of genes (or groups of genes) to different locations of genome. 1 in every thousand- clein something disease (extra chromosome in men), phenotypic features of women on men. Directional selection smaller body = more advantageous (island dwarfisms) bc of less food.
