Which Best Describes How Meiosis Contributes to Genetic Variation

Primary succession occurs in an area that has never before been colonized. Genetic variation lays the foundation for organisms to have genetic diversity which contributes eventually for biodiversity through species diversity.

7 2 Meiosis Concepts Of Biology 1st Canadian Edition

Genetic variation is simply the variation in alleles of genes in the gene pool of a species or a population.

. The term epigenetics describes heritable patterns of phenotypic variationthat is stable transmission of information through mitosis or meiosisthat are not solely attributable to differences in DNA sequence. Aquatic communities living in 1. Homologous chromosomes move toward opposite.

Which of the following statements best describes the advantage that sexual reproduction likely provides over asexual reproduction. The process by which that occurs is called ecological succession. Biodiversity includes genetic variation within a species in addition to species variation in different habitats and ecosystem types e.

Although energetically more costly than asexual reproduction sexual reproduction leads to different combinations of alleles that could provide adaptability in a changing environment. Nov 22 2019 Ecological succession is the change. It is distinguished from genetic variability which describes the tendency of genetic characteristics to vary.

Epigenetics is often used more broadly to describe changes in chromatin state chromatin modification and DNA methylation without regard for heritability.
