Hardy-Weinberg Calculations Flashcards
1
Q
Frequency
A
how common something is; usually expressed as a decimal percentage; e.g. an incidence of “2 in 5” gives the same information as a frequency of 0.4 or 40%
2
Q
Hardy-Weinberg equation
A
an equation used to determine the frequency of genotypes:
p2 + 2pq + q
where p = frequency of the dominant allele
q = frequency of the recessive allele
If the frequency of genotypes is known, the equation can be used to work backwards to find the frequency of alleles in the gene pool
3
Q
The frequency of the homozygous genotype in the population
A
p2 = f(AA)
4
Q
The frequency of the heterozygous genotype in the population
A
2pq = f(Aa)
5
Q
The frequency of the homozygous recessive genotype in the population
A
q2 = f(aa)
