It is not an equation, but q2 meaning q^2 represents q being multiplied by itself.
p2+2pq+q2=1
p and q represent the frequencies of two types of alleles.
rutherford
If restricted to integers, then p is -1, 0 or 1. If restricted to real numbers, then any number in the interval [-1,1]. If not so restricted then any number you like.
Even
p2+2pq+q2=1
p and q represent the frequencies of two types of alleles.
p2 + 2pq + q2 = 1q2 + 2pq + (p2 - 1) = 0q = 1/2 [ -2p plus or minus sqrt( 4p2 - 4p2 + 4 ) ]q = -1 - pq = 1 - p
p represents the square root of the frequency of the homozygous genotype AA.
The Hardy-Weinberg equation is as follows: p2 + 2pq + q2 = 1 p & q represent the frequencies for each allele.
p represents the square root of the frequency of the homozygous genotype AA.
rutherford
The frequency of the homozygous 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
