What type of reproduction produces genetic variation?
The type of cell division is meiosis
How does meiosis contribute to the variation in a species?
During meiosis crossing over takes place between homologous chromosomes. Thus genetic material get interchanged and 50 % new combinations are obtained after each meiotic cell division. Thus, meiosis brings heritable variation in the gametes.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What two factors introduce genetic variation during the process of meiosis?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.
Does meiosis have variation?
During meiosis, genetic recombination of homologous chromosomes occurs. So meiosis does result in genetic variation. After prophase I, during which crossing over occurs, every chromosome will have some maternal DNA and some paternal DNA.
Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.
What type of reproduction produces genetic variation?
The type of cell division is meiosis
Why does meiosis exist?
Meiosis exists to ensure genetic variation between offspring. As long as the genes are being passed on, interchanged, and reselected, a species will remain adaptable.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
How does meiosis contribute to the variation in a species?

Genetic variation in bacterial populations cannot result from?
meiosis, Ap BIO
How does meiosis create variation?
Meiosis creates genetic variation through the production of 4 haploid daughter cells, each with random genetic combinations. Meiosis also creates genetic variation through the process called crossing over, where chromosome segments are exchanged.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
How does meiosis aid in evolution?
contributes to genetic variation.
What are the importances of meiosis?
Meiosis produces four haploid daughter cells that are not identical.Meiosis results in genetic variation.
Does meiosis have variation?
During meiosis, genetic recombination of homologous chromosomes occurs. So meiosis does result in genetic variation. After prophase I, during which crossing over occurs, every chromosome will have some maternal DNA and some paternal DNA.
