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.
What type of reproduction produces genetic variation?
The type of cell division is meiosis
Does asexual reproduction contribute to sexual variation?
No. Asexual reproduction provides no diversity, as it creates an exact copy of the organism. Sexual reproduction, on the other hand, provides diversity by using and combining different genes each time to create an entirely new version of the organism.
What is the relation between meiosis and variation?
Meiosis is a crucial process in sexual reproduction that generates genetic variation among offspring. During meiosis, homologous chromosomes undergo recombination through crossing over and independent assortment, which shuffle alleles and create new combinations of traits. This variation is essential for evolution and adaptation, as it increases the genetic diversity within a population. Ultimately, the unique combinations of genes produced through meiosis contribute to the differences observed among individuals.
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.
What does meiosis do for species?
Meosis creates gametes (reproductive cells) and allows genetic variation of the species
Does crossing over during meiosis contribute to genetic variation?
Yes, crossing over during meiosis contributes to genetic variation by exchanging genetic material between homologous chromosomes, leading to new combinations of genes in offspring.
What specific meiotic events contribute to meiosis leads to significant genetic variation while mitosis does not?
may be its genetical diffence
Does amoeba have separate sexes?
No. They are asexual. Which means they separate in order to reproduce by meiosis creating no variation among the species
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.
How does crossing over during meiosis contribute to genetic variation?
Crossing over during meiosis is a process where genetic material is exchanged between homologous chromosomes. This contributes to genetic variation by creating new combinations of genes, leading to offspring with unique traits.
Does asexual reproduction contribute to sexual variation?
No. Asexual reproduction provides no diversity, as it creates an exact copy of the organism. Sexual reproduction, on the other hand, provides diversity by using and combining different genes each time to create an entirely new version of the organism.

Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for 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.
Why is variation good for a species?
Sometimes positive variation can improve some ability of the species adapted to the environment. For example, a kind of virus can be killed by medicine A. A small part of the virus has some variation that make it can be alive with medicine A. The species of the virus can exist in future, or it will disappear in the future in the environment full of medicine A. Besides, positive variation can provide some capacity for the species to get more resource in the competition. Of course, there is negative variation that might contribute to the disappearance for the species. That is just another side of variation.
What causes genetic variation in a species?
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
