1
microevolution
an evolving population is one that is showing genetic change over generations, if actual ratios dont match H-W ratios, then the population is evolving
2
mechanism of Microevolution
natural selection, genetic drift, gene flow
3
genetic drift
genetic frequency Cheadle to random events. Outcomes are random changes in allele frequency in either direction, reduces diversity, alleles may become fixed or lost
4
bottleneck effect
an event drastically cuts population size, the gene pool of survivors is random, some alleles may be lost
5
gene flow
alleles move in and out of the population from the migration of adults, dispersal of gametes, seeds, etc. this adds diversity to population and reduces different between populations
6
directional selection
shifts character mean value to one direction
7
disruptive selection (diversifying)
intermediates are les fit than the extremes, so the
8
stabilizing selection
intermediate types more foot than extremes
9
binomial nomenclature
aka the scientific name for species
10
taxonomy
grouping species together based on similarities
11
taxonomic levels
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (Dashing King Philip Came Over For Good Soup)
12
clade
a the species in a clade share homologies
13
orthologous genes
are inherited from common ancestor
