What does the letter Q stand for in the Hardy Weinberg equation?

The Hardy-Weinberg equations are. p + q = 1. p² + q² + 2pq = 1. p stands for the frequency of a dominant allele in a population. q stands for the frequency of a recessive allele in a population.Click to see full answer. Herein, what does the Q stand for in the Hardy Weinberg equation?In the Hardy- Weinberg equation, the letter q stands for homozygous recessive alleles.Secondly, what does 2pq mean in Hardy Weinberg? Explanation: In the Hardy-Weinberg equilibrium equation ( p2+2pq+q2=1 ), the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium. The term p2 represents the frequency of dominant homozygotes (AA) and the term q2 represents the frequency of recessive homozygotes (aa). Also, how do you find q in Hardy Weinberg? To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers). The frequency of the recessive allele. The frequency of the dominant allele. The frequency of heterozygous individuals. What do p and q symbolize?When Hardy-Weinberg equilibrium is met the following equation is true: p2 +2pq + q2 = 1. Where p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the recessive genotype and 2pq is the frequency of the heterozygous genotype.
