Genetic variation in a population increases the chance that some individuals will survive. • Genetic variation leads to phenotypic variation. • Phenotypic variation is necessary for natural selection. • Genetic variation is stored in a population’s gene pool. – made up of all alleles in a population ...

This reaction, which appears to be an immune response similar to hives, is thought to be due to the action of a recessive gene (h). The population of this tropical ...
