					Mitosis and Meiosis Study Guide

Define binary fission.
Understand that reproduction happens both asexually and sexually.
Define centromere, chromatid, and homologous chromosome.
Describe the chromosomes in your body.
Explain why the male determines the sex of the child.
Recognize XX-egg as female and XY-sperm as male.
Identify the number of chromosomes in somatic cells in the gamete cells.
Differentiate between haploid and diploid.
Discuss what happens if nondisjunction occurs.
Describe mutations caused by deletion, duplication, inversion, and translocation.
Define trisomy and associate this disorder with Down syndrome.
Identify (sequence) and describe the stages in the cell cycle.
       Interphase (G1, S, G2)
       Mitosis (prophase, metaphase, anaphase, telophase) =M
       Cytokinesis (C)
Identify the phase where cells are resting or not dividing.
Discuss what happens at the G1 and G2 checkpoints.
Explain how the cell cycle is monitored.
Identify what controls the cell cycle in eukaryotes.
Describe how normal cells become cancer cells.
Define spindle fiber and microtubule.
Recognize diagrams of each of the 4 phases (PMAT) in mitosis.
Recognize drawings showing the beginning and end of both mitosis and meiosis.
Explain what plants cells do during cytokinesis.
Recognize a diagram of the meiosis phases.
Differentiate between meiosis I phases and meiosis II phases.
Tell when genetic recombination occurs.
Discuss why segments of DNA must be exchanged.
Describe the three recombination processes that provide new genetic combinations:
       Independent assortment
       Random fertilization
       Crossing over
Explain why genetic diversity is important.
Differentiate between spermagenesis and oogenesis.
Know that meiosis produces sperm and egg cells.
Define ovum and explain why it divides unequally.

Know that the zygote undergoes meiosis to create more haploid cells during the
haploid life cycle.
