The Hardy-Weinberg equation is expressed as p2 + 2pq + q2 = 1.0. In biology, null models attempt to describe what would happen in a system that is not influenced by any biological processes of interest.

If you remove all the homozygous dominants and allow the remaining population to reproduce (again under Hardy-Weinberg conditions), what will be the frequency of homozygous dominants in the … WebHardy-Weinberg Equations p 2 2 pq + q 2 = 1 p = frequency of allele 1 in a population p q = 1 q = frequency of allele 2 in a population Metric Prefixes Factor Prefix Symbol 10 9 giga G 10 6 mega M 10 3 kilo k 10 –1 deci d 10 –2 centi c … WebYes Hardy-Weinberg is mainly used to calculate the expected frequency assuming: no mutations, no gene transfer, random mating, large population, and no selection. However if we know the actual frequency of the homozygotes (i.e. p^2 and q^2) in the actual population we can compare to an expected value. So p+q should = 1 , in a real population if ... office table and chair size
