Misconceptions about natural selection - Understanding Evolution

WebNatural selection occurs if the following 4 criteria are met. Overproduction, a species produces more offspring than will survive to maturity. Genetic diversity, individuals within the species population are genetically slightly different from each other. Struggle to survive, individuals of a population must struggle to access resources;such as ... WebIn a large population, where there is random mating and no mutation, neither migration nor selection, allele and genotype frequencies become stable in one generation. This is called the Hardy-Weinberg equilibrium law, which is a crucial genetic model for the conservation of the population diversity and the genetic study of natural populations.
