Hi there,

Here you go :)

1.
Meiosis Mitosis

Produces: four haploid daughter cells two diploid daughter cells
Genetically: different identical
Function: Growth, Repair, asexual Reproduction Cellular Reproduction (cell division during which the cell nucleus divides)
Creates: Sex cells only Makes everything other than sex cells (Somatic Cells)
Occurs in: Humans, animals, plants all organisms

Meiosis is a special process in cellular division where cells are created containing gene patterns of different types and combinations with 50% of the number of chromosomes of the original cell. Meiosis is used in sexual reproduction of organisms to combine male and female, through the spermazoa and egg, to create a new, singular biological organism.

C-value refers to haploid amount of DNA

n - number of chromosome sets

The S (Synthesis) period is where DNA ...
