|
gene flow
|
flow of alleles from one population to next population. like the one island migration model
|
|
|
island model migration
|
deal with flow of alleles from continent to island. proving that migration can interupt hw conditions
|
|
|
inbreeding
|
f. mating within your genetic family that can lead to deleterious alleles accumaltating.
|
|
|
fst
|
coefficent of standard variance. measure heterozygosity of genetic differences between populations
|
|
|
effective population size
|
total number of random mating indviduals within a population that loose genetic variance via drift at same rate as an observed actual population. total number of of mating females and males.
|
|
|
sexual selection
|
different modes or traits that increase an individuals chance to mate
|
|
|
phenotypic varitability
|
total varitablity within a individual in a population for variations of a phenotype
|
|
|
intrasexual selection
|
males control if they get to mate by fighting other males for females
ie pride of lions |
|
|
multilocus genotype
|
many genotypes can be acredited to many different loci on a differente gene for a trait
|
|
|
population admixture
|
mixing of 2 populations that can cause linkage disequilbrium
|
|
|
directional selection
|
indvidual fitness tends to increase or decrease with the value of phenotypic trait.. result in steady evolutionary change
|
|
|
parthogenesis
|
organism is born from an unfertilized egg
|
|
|
mullers ratchet
|
statement tht in asexual populations alterations in deleterious allels accumulate much faster. more homozygous recessive genes.
|
|
|
genetic drift
|
sampling error in the production of number of zygotes for a gene pool.
|
|
|
creates linkage disequilbrium
|
selection on multilocus gentoype
genetic drift population admixture |
