The Hardy-Weinberg equation is as follows: p2 + 2pq + q2 = 1 p & q represent the frequencies for each allele.
The Hardy-Weinberg Equilibrium equation: p2 + 2pq + q2 = 1 p is frequency of dominant allele A q is frequency of recessive allele a p + q always equals 1 pp or p2 is probability of AA occurring qq or q2 is probability of AA occurring 2pq is probability of Aa occurring (pq is probability of Aa, qp is probability of aA, so 2pq is probability of all heterozygotes Aa) These add up to 1 because they represent all possibilities. The frequency of the homozygous recessive genotype
Allele frequency is inherently stable.
allele frequency
To predict changes in allel frequency
If you have the alleles A and a, then the The hardy-weinberg equation is: A2 + 2Aa + a2 = 1 where a and A represent allele frequencies. So A2 would be the genotype frequency for AA. 2Aa is the genotype frequency for Aa. And a2 is the genotype frequency for aa. Plug in whatever information you have into the equation and you can probably come up with an answer. Save
The frequency of the homozygous dominant genotype.
The frequency of the homozygous dominant genotype.
The frequency of the homozygous recessive genotype.
To determine how allele frequency changes
The frequency of the homozygous recessive genotype.
p is the value of an allele frequency.
p represents the square root of the frequency of the homozygous genotype AA.
p represents the square root of the frequency of the homozygous genotype AA.
the frequency of the heterozygous dominant genotype
The Hardy-Weinberg Equilibrium equation: p2 + 2pq + q2 = 1 p is frequency of dominant allele A q is frequency of recessive allele a p + q always equals 1 pp or p2 is probability of AA occurring qq or q2 is probability of AA occurring 2pq is probability of Aa occurring (pq is probability of Aa, qp is probability of aA, so 2pq is probability of all heterozygotes Aa) These add up to 1 because they represent all possibilities. The frequency of the homozygous recessive genotype
the phenotype frequency does not change
The Hardy-Weinberg rule stated that if the frequency of an allele in a population at genetic equilibrium is .45. The frequency of that allele would be .45 in the next generation.
