The AIM of meiosis is to create cells with half the number of chromosomes, so that during fertilization, each parent could contribute their own set of genes to the offspring and thereby conserve the number of chromosomes of a species and promote variation. Ploidy refers to the number of chromo...

Meiosis, on the other hand, is used for just one purpose in the human body:the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell. When and where does meiosis occur in the human body? Meios...
Meiosis; Chapter 6.2 I. Purpose of meiosis is to create a gamete that is haploid (half the normal number of chromosomes), from a diploid cell (complete. Meiosis and Sexual Reproduction. Meiosis. Oocyte Biology: Do the Wheels Fall Off with Age? Meiosis. Mitosis: Too Much of a Good Thing ...
Reproduction occurs in humans with the fusion of two haploid cells (gametes) that create a zygote. The nuclei of both these cells fuse, bringing together half the genetic information from the parents into one new cell, that is now genetically different from both of its parents....
Cell division is the process that cells use to duplicate themselves. There are two main types of cell division: mitosis andmeiosis. Mitosis is the process that cells use to duplicate themselves for growth and repair. Meiosis is the process that cells use to create gametes, such as sperm and...

meiosis is not at all optimized to create new gene combinations, as Holliday junctions can be resolved with and without cross-over. The frequencies of non-crossovers were shown to be higher than those of cross-overs, but only the latter create new gene combinations in flanking regions, which ...
