By recombining the genetic material in two ways with a third way furthering variation.
1. The independent orientation of the chromosomes during prophase I of meiosis.
2. Crossing over between chromosomes in prophase I of meiosis.
3. Random fertilization of gametes.

How does meiosis aid in evolution?
contributes to genetic variation.
Genetic variation in bacterial populations cannot result from?
meiosis, Ap BIO
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
How does meiosis contribute to the genetic traits of a ReeBop offspring?
Meiosis produces the genetic material that will be paired with the genetic material of the partner. This will determine the traits the baby inherits.
Under what circumstances would crossing over during meiosis not contribute to genetic variation among daughter cells?
when homologous chromosomes are the same. also, in the case of a double cross over.
How point mutation frame shift mutation and meiosis contribute to genetic variation?
Nicely. Do your project on your own!
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
What specific meiotic events contribute to meiosis leads to significant genetic variation while mitosis does not?
may be its genetical diffence
Which description does not apply equally well to both sexual and asexual spores?
The ability to undergo meiosis and produce genetic variation does not apply equally well to both sexual and asexual spores. Sexual spores are formed through meiosis, which shuffles genetic material and leads to genetic variation. Asexual spores, on the other hand, are produced by mitosis and do not contribute to genetic diversity.
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.?
What type of reproduction produces genetic variation?
The type of cell division is meiosis
How does meiosis aid in evolution?

Genetic variation in bacterial populations cannot result from?
meiosis, Ap BIO
What phase in meiosis increases genetic variation?
Crossing-over
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 does meiosis provides for genetic variation mean?
The genes decide how we look and a lot about how we are. If there wasn't genetic variation we'd all be the same.
