What Recombination occurs during .?
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA

What are the end results of mitosis and meiosis?
1) Mitosis occurs in body cells and produces two diploid (2n) daughter cells that are genetically identical for growth and repair. Meiosis occurs in the gonads and produces four haploid (n) daughter cells that are genetically unique for reproduction. 2) Meiosis requires two cycles to halve the chromosome number.. The first cell division of meiosis called meiosis I is similar to mitosis.. The second cell division halves the chromosome number from 2n to n.. This is required to produce gametes (cells with n number of chromosomes - sperm or ova) so that when the gametes join together during fertilization they produce a zygote that is 2n. 3) Crossing over during meiosis increases the genetic variation of the gametes and thus the next generation.. Crossing over occurs in prophase I of meiosis when homologous chromosomes pair up in tetrads and non-sister chromatids swap pieces of DNA.. This creates unique chromosomes.. Variation is also increased by the independent assortment of chromosomes during meiosis (a gamete can receive the paternal chromosome or maternal chromosome for each chromosome) and random fertilization (any sperm can fertilize any egg)..

How does meiosis produce genetic variability?
There are three sources of genetic variation in meiosis: 1) Independent assortment = like shuffling a deck of cards and dealing out half the deck 2) Crossing over = homologous chromosomes swap parts, making new combinations 3) Random fertilization = only one sperm cell makes it into the egg
How recombining of genetic information leads to offspring that exhibit genetic variability?
Recombining of genetic information (crossing over) during prophase I of meiosis results in every chromosome being a combination of the person's mother's and father's genetic information. Recombination of genetic information in an offspring takes place at the time of gametic union forming the zygote. The genetic variability depends on the extent of heterozygocity present in the population of that species. Role of crossing over is limited to the extent of frequency of genes present in an individual to produce variety of gametes.
When homologous chromosomes swap pieces during meiosis this is called?

Why do variations occur?
Variation or traits are due to changes in the genes. The genes are found in the DNA and when they replicate, the process doesn't always work correctly. We have called these mutations. A few are positive for the species, some are negative (and are not passed on) and a few do not make any change at all.
