number of chromatids in the daughter cells formed by first division 46
number of chromosomes in daughter cells formed by first division 23
number of chromosomes in daughter cells of second division 23
number of haploid cells formed by meiotic division of parent cell 4
Produces haploid cells from diploid cells. meiotic cell division
Cell division in prokaryotes. binary fission
Enables growth in multicellular organisms. mitotoic cell division
______ cells (2N) have two complete sets of chromosomes. Diploid
The body cells of animals are diploid.
______ cells have one complete set of chromosomes. Haploid
In animals, gametes (sperm and eggs) are haploid.
_________ chromosomes are two chromosomes that are the same Homologous
______ organisms have two of each chromosome diploid
In a diploid, Each of the pairs is a ____ pair homologous
Mitosis produces two daughter cells that are identical to the parent cell.
If the parent cell is haploid (N), then the daughter cells will be haploid.
If the parent cell is diploid, the daughter cells will be also be diploid.
N --> N
2N --> 2N
Meiosis produces daughter cells that have __ ___ the number of chromosomes as the parent cell. one half
2N --> N
Gametes (sperm and eggs) are haploid.
Meiosis is in sex organisms because the fusion of two gametes/fertilization doubles the no. of chromosomes.
Meiosis involves two divisions producing a total of ____ daughter cells. four
In meiosis I, chromosomes in a diploid cell resegregate, producing _____ daughter cells. four haploid
It is this step in meiosis that generates genetic diversity. meiosis I
