Mitosis
In this stage, chromosomes first become visible.
Prophase
– Human body cells have this many chromosomes.
46
– In males, meiosis produces this many sperm.
4
DNA replicates during this phase.
The S phase
Meiosis produces this many cells.
4
Sister chromatids separate in this stage.
Anaphase
– A pair of identical chromatids joined together are called this.
sister chromatids
– In females, the extra cells that do not become eggs are called this.
polar bodies
Cells spend most of their life in this stage.
interphase
Meiosis creates cells with this chromosome number (haploid or diploid?).
haploid
Chromosomes line up at the center of the cell.
Metaphase
– Two sets of chromosomes means the cell is this.
diploid
– Gametes must be haploid so they can form this after fertilization.
diploid zygote
The S phase stands for this word.
synthesis
crossing over happens during this stage of meiosis I.
prophase 1
The nuclear membrane reforms during this stage.
Telophase
– Homologous chromosomes form this structure in meiosis I.
tetrad
– Mitosis is used for this in multicellular organisms.
Growth and Repair
The division of the cytoplasm is called this.
cytokinesis
This process mixes up chromosome pairs randomly.
independent assortment
This process produces two identical diploid cells
mitosis
– Haploid cells contain this many sets of chromosomes
one set
– Meiosis is used for this type of reproduction.
sexual reproduction
Cancer is caused by this problem with the cell cycle.
uncontrolled cell division?
Crossing over increases this.
genetic variation
