How does meiosis play a role in the evolution of a species A. It increases the reproduction rate of the species

B. it increases the amount of genetic variation in the species

C. It reduces the amount of competition between members of the species

D. It increases the ability of individuals in the species to obtain resources

The correct answer is - option B. it increases the amount of genetic variation in the species.

Explanation:

Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.

The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
