Meiosis Pgs Human body cells have 46 chromosomes Meiosis - General Overview Sexual Reproduction and Genetics Each parent contributes 23 chromosomes.
2//12-Pick up your book. **Take out your GATTACA & EOCT Review Wksts.** Copy & answer the following questions on a blank sheet of paper. 1. How do you.
The cell cycle and mitosis. Cells constantly reproduce exact duplicates of themselves. Why? Replacement Repair Growth.
Meiosis. Meiosis is the type of division which: 1. Reduces the chromosome # from diploid to haploid 2. Is used to produce gametes: eggs and sperm.
Mitosis –vs- Meiosis Test Review. If the HAPLOID number of an organism is 12, what would the diploid number be? 24.
Cell Cycle: M Phase Mitosis and Cytokinesis. Cell Division (M phase) Occurs in two stages – Mitosis (nuclear division) – Cytokinesis (cytoplasmic division)
Cell Division Mitosis Chapter 10. Why do cells divide, rather than continually grow forever? The larger a cell becomes, the more demands the cell places.

Cell Growth and Division Mitosis and Meiosis. Cell Growth When an organism grows, the number of cells increase but the size of each cell remains small.

Meiosis and Sexual Reproduction. Sexual Reproduction Diploid Cell A cell that has chromosomes located in similar pairs. These cells are called body cells.
Meiosis The process in which the nucleus of a cell completes two successive divisions that produce four nuclei, each with a chromosome number that has.
