Evolution is defined as a change in allele frequencies in a population of organisms over time. Then, the scientists took out all of the homozyg recessives and after a long time measured the amount and frequency of each genotype in the population, meaning now it is not in HW equil, and there are only heterozygous and homozyg dom.
