What percentage of the alleles for hair length in this population are the long hair (h) allele?

The correct answer to this question is 30%. This type of question could be found on both a math or science test. It is related to the Hardy–Weinberg Principle. This principle is also known as HWE or the Hardy–Weinberg law. It is named after mathematician G. H. Hardy and gynecologist Wilhelm Weinberg.

Nowadays, the test is primarily used to test matting that is non-random. For a population to remain at Hardy-Weinberg equilibrium under the Hardy-Weinberg principle, five conditions must be met. These conditions include random mating, a large breeding population, no natural selection, no immigration, and no change in allelic frequency.
