Mitosis Vs Meiosis definitions

# Definition Sets
1 mitosis: one division forming 2 identical cells (clones); meiosis: two divisions forming 4 genetically different cells 15 sets
2 mitosis is a type of cell division that gives rise to two daughter cells, each with identical chromosomes, genotypes and involves duplication of chromosomes and one cell division. meiosis is the process of replication undergone by the ovaries and sperm--involves one one duplication and one division of chromosomes, the cells created are divided again so that the offspring only receives half of the chromosomes. 8 sets
3 -mitosis: produces two genetically identical diploid cells, organism uses to grow and replace cells, for asexual reprod. -meiosis: produces 4 haploid cells from one diploid, sexually reproducing organisms use to prod. gametes 5 sets
4 mitosis maintains chromosome #, meiosis halves the chromosome mitosis basis of increases in body size during development, replacement of damaged cells, meiosis does not occur during these processes mitosis part of asexual reproduction and meiosis sexual reproduction 3 sets
5 mitosis - genetic material duplicated meiosis: mito - two identical diploid (2n) daughter cells meiosis - 4 diff. haploid (n) gametes 3 sets
