population genetics Flashcards
define gene pool
the total information for all the genes and alleles of the breeding individuals in a population at a particular time
how does the gene pool change
the gene pool changes from generation to generation
what is allele frequency
proportion of organisms in population carrying a particular allele
what can affect population
population bottle neck
define population bottle neck
a diverse population drastically reduced by non selective event
give an example of a non selective event
volcano eruption
what is the founder effect
when a new population is founded out of an original population
what is genetic drift
a change from one generation to the next
what is the hardy-weinberg principle used for
to calculate the proportion of alleles in a population
what is the hardy weinberg equation
p^2+2pq+q^2=1
