MITOSIS: is the reproduction of body cells (somatic cells), diploid, two daughter cells produced, chromosomes line up singly in metaphase, one nuclear division, produces cells for growth and repair, daughter cells have two sets of chromosomes (pairs), daughter cells are genetically identical to the parent cell
MEIOSIS: produces sex cells (gametes), haploid, four produced, two nuclear divisions, produces cells for sexual reproduction, daughter cells have only one member of each pair of chromosomes, daughter cells have one half of the genes from the parent cell, generates genetic diversity through crossing over and random seperation of homologous pairs of chromosomes.

This video is great if you are confused and has a cool background music.
ReplyDeleteMITOSIS-
ReplyDeleteI thought that the animation could have been more clear about telophase, when the cytoplasm pinches and the two daughter cells are created. It confused me a little because it didn't show that happening, it just showed the two daughter cells appearing.
