#1
Front (Question)

what is a gene pool?

Back (Answer)

all of the alleles of all the genes of all the individuals in a population at a given time

#2
Front (Question)

what is allelic frequency?

Back (Answer)

the number of times an allele occurs within the gene pool

#3
Front (Question)

what assumptions need to be made when applying the hardy-weinburg principle / how does evolution not occur? (7)

Back (Answer)

• mutation is not occuring • natural selection is not occuring • population is infinitely large • all members of the population breed • all mating is totally random • everyone produces the same number of offspring • there is no migration in or out of the population

#4
Front (Question)

what is the hardy-weinburg equation?

Back (Answer)

p² + 2pq + q² = 1

#5
Front (Question)

how is the hardy-weinburg equation created based on a genetic equilibrium?

Back (Answer)

• for a population in genetic equilibrium, p + q = 1 • sum of frequencies of both alleles = 100% • (p + q)² must be 1 so p² + 2pq + q² = 1

#6
Front (Question)

p, q, p², 2pq, q² what do the different parts of the hardy-weinburg equation stand for?

Back (Answer)

• p = freqency of dominant allele • q = frequency of recessive allele • p² = frequency of AA (homozygous dominant) • 2pq = freqency of Aa (heterozygous) • q² = freqency of aa (homozygous recessive)
