members of a population so similar they breed toghther
species
random change in allele frequencies
genetic drift
1 condition required to maintain genetic equilibrium
random mating
situations in which allele frequencies remain constant
genetic equilbrium
who dicovered organisms well suited to their habitat
darwin
small islands close together
galapagos
traits controlled by 1 gene
singlegene
further back is common ancestor to all living things
common ancestor
individual has two of the same forms of the allele
homozygous
individual has 2 different forms of the allele
heterozygous
sometimes alleles become more or less frequent by chance
genetic drift
when allele frequency changes due to migration
founder effect
when populations are seperated by geographical barriers
geographical iso
when the reproduction occurs at different times
temporaliso
when population capable of breeding do not dur to differnces in rituals
behavioraliso
