Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation, and that variation must be able to be passed on to offspring.

Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.genotype. (jĕn′ə-tīp′, jē′nə-) n. 1.

Gregor Mendel set up a dihybrid cross with one pea plant from the parental generation (P) producing round yellow peas and the other pea plant producing wrinkled green peas.Heritable variation in climate resistance traits is essential for adaptive evolution; however, the rate of evolution will also be determined by tradeoffs in the response to individual stressors. Similar to the findings of Wright et al .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. There should be a presence of heritable variation. There should be a different fitness rate among individuals to initiate the “survival of the fittest.” 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 instructions for building proteins.

Evolution is the process by which species change over time and adapt to their environment. Without heritable variation, there would be no genetic diversity that could lead to the emergence of new traits and new species.

Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color. Rather, a genetic mutation causes a difference in fur color, which may help that rabbit hide better in its environment.
