Gene flow
is the passage and establishment of genes typical of one population in
the genepool of another
how gene flow?
natural or artificial hybridization and backcrossing
levels of population
Individual organisms.
Subpopulations.
Total population.
sub populations can have different…..depending on…
genetic links
degree of gene flow
why is there subpopulations?
ecological factors
behavioural
structure of population affects
extent of genetic variation and its
patterns of distribution.
structured population if
genetic drift is occurring migration does not happen uniformly
mating is not random
allele freq
quantifying variation
how common an allele is
allelic differences at 1 locus
This genetic variation needs to be quantified for different … and for different
……..
genes
individuals/populations
calculating allele freq
no. of desired allele/all alleles
homo+half hetero
sample should be….or the results are just..
100+
estimates
genotype freq
freq of a certain genotype in a population
relation between allele freq and genotype freq determined by
breeding system type
natural breeding system
random mating has..
genotype freq is used to..
freq with alt geneotypes
expected genotypes patterns
estimate self pollination
hardy weinberg rules
NO natural selection
NO mutations
NO sexual selection
NO migration
Infinite population size
