Mitosis produces two daughter cells that are genetically identical to the original parent cell. Therefore there is no variation (except when things like mutations happen).
Meiosis produces haploid daughter cells - this means that they only contain half the number of chromosomes (or genetic material) as the original parent cell. These cells then go on to participate in sexual reproduction and fuse with a different haploid cell. Therefore the resulting organism recieves half the genetic material from each - and is identical to neither.
What else can I help you with?
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
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 phase in meiosis increases genetic variation?
Crossing-over
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.
Genetic variation in bacterial populations cannot result from?
Genetic variation in bacterial populations cannot result from sexual reproduction, as bacteria typically reproduce asexually by binary fission.
What is the result of meiosis in terms of genetic variation and the formation of haploid cells?
The result of meiosis is the formation of haploid cells with genetic variation. Meiosis creates four haploid cells, each with a unique combination of genetic material due to processes like crossing over and independent assortment.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
What kind of impact does crossing over create in genetic variation during meiosis?
Crossing over during meiosis creates genetic variation by exchanging genetic material between homologous chromosomes, leading to new combinations of genes in offspring. This increases genetic diversity and can result in unique traits in individuals.
Does the independent assortment of genes during meiosis cause genetic variation?
Yes, the independent assortment of genes during meiosis does cause genetic variation.
What is the significance of genetic variation after meiosis?
Genetic variation after meiosis is significant because it leads to the creation of unique offspring with diverse traits. This variation is important for evolution and adaptation to changing environments.
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.
