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 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.?
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.

Chromosomes exchange genetic information through the process of what?
Chromosomes exchange genetic information during a process called crossing over. This occurs during meiosis
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing Over.
Is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing Over.
What is the important event during meiosis that results in genetic variation?
Crossing-Over
Is Interkinesis is the most important process that increases variety in human gametogenesis?
No, interkinesis has nothing to do with genetic variation. The two features of meiosis that increase genetic variation in gametogenesis are (a) crossing over during prophase I, and (b) the independent assortment of chromosomes during anaphase I and anaphase II.
What happens during synapsis in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. During synapsis is when tetrads form.
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
What is relationship between gametes and genetic variation?
