Vocabulary. Genetic variation refers to differences among the genomes of members of the same species. A genome is all the hereditary information—all the genes —of an organism. For instance, the human genome contains somewhere between twenty and twenty-five thousand genes. Genes are units of hereditary information, and they carry ...The result shows that heritable variance determining potential response to selection is the variance among individuals in the heritable quantity that determines the population mean trait value, rather than the usual additive genetic component of phenotypic variance. It follows, therefore, that heritable variance may exceed phenotypic variance ...Natural selection takes place in the following conditions: There should be a struggle for existence, which means that there are more individuals that are born than can survive.
