What are the results and implications of meiosis?
Meiosis is the process of dividing a diploid cell into haploid cells. The main results of meiosis are four haploid cells. Genetically, these cells differ from the diploid cell and from each other.
What is the result of crossing over?
The crossing over alleles is critical to the survival and genetic diversity of a species. The results of the random crossing over of alleles is that the offspring will have chance inheritance of certain characteristics from their parents (as opposed to being genetic clones with no diversity). The diversity of phenotypes are among the major manifestations of random crossing.
What is the type of cell division that occurs in reproductive cells and has to division?
Meiosis occurs in reproductive cells and is called reduction division because of presence of single set of chromosomes. It results in the formation of four daughter cells. Meiosis is a source of new genetic variation.
What is genetic combination?
in meiosis, prophase 1( the longest stage ) there is a particular stage called PACHYTENE where there is crossing of the chromatids ( the arms of the chromosome) belonging to one paternal and one maternal. there is subsequent breakage and rejoining of the chromatids which results in variation called as genetic recombination.
Why is it necessary for homologous to pair during meiosis and not desirable for them to pair in mitosis?
to cross over which results in the genetic recombination
What are the importances of meiosis?
Meiosis produces four haploid daughter cells that are not identical.Meiosis results in genetic variation.

What results in the most diverse offspring?
Sexual reproduction leads to variety in offspring.
Which type of reproduction results in the greatest amount of genetic variation?
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.

What is meiosis about?
Meiosis is Sexual Reproduction, unlike Mitosis, that is responsible for cell growth and other functions. Meiosis has the same phases as Mitosis except that it undergoes those phase twice (Meiosis l and ll). This results in 4 daughter cells, unlike Mitosis which results in only 2 daughter cells. Also, in Mitosis the daughter cells are identical to the original cell, while in Meiosis, it increases genetic variation, because it has characteristics of both parent cells.
What is genetic combination?
in meiosis, prophase 1( the longest stage ) there is a particular stage called PACHYTENE where there is crossing of the chromatids ( the arms of the chromosome) belonging to one paternal and one maternal. there is subsequent breakage and rejoining of the chromatids which results in variation called as genetic recombination.
Why synapsis is the key to the diversity that results from meiosis?
The purpose of synapsis is to increase genetic variability
Why is reductive division and old name for meiosis?
As it results in reduction in genetic content of cells
During meiosis crossing-over gene exchange between chromosomes may occur Crossing-over usually results in?
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
What genetic recombination in meiosis results in daughter cells D-------- from each other and from the parent cell?
Different
