Document Summary

Pair (or series) of different forms of a gene. O can occupy the same location on a particular chromosome + control the. O how common a certain allelle is in a population. O origin of 2 or more species resulting from divergent evolution of populations that are geographically isolated from each other. Organisms ranges are entirely separate, do not occur in any one place together. Creates 2 species that are similar, but one is a changed version of the other. O more of than the usual number of chromosomes, x > 2n. O results from the interbreeding of different species. O more than 2 sets of chromosomes, x > 2n. Biological species (taxonomy = kingdom/phylum/class/order/family/genus/specie: no universal agreement for what it is, living animal or plant, e. g. 1. 3 1. 5 (mi) named to date (about 1/10th) of total. 10:1 error ratio b/c others = not seen. Bottleneck effect (hardy-weinberg principles genetic drift) Form of gene drift: variability in genes = .
