Fall 2007
Chapter 9:
You should know what binary fission is.
You should know what occurs in the three basic
components of the cell cycle:
Interphase, Mitosis, and Cytokinesis. Know which of these
takes the longest period of time to complete.
You should know what happens in each specific component
of the cell cycle including:
G1, S, and G2 phases of interphase;
prophase, metaphase, anaphase, and telophase of mitosis. Be able to visually
recognize all stages of mitosis and all specific structures that we discussed.
These include spindle fibers, astral rays, chromosomes, cell plate, and
cleavage furrow.
Know the following terms: Chromosomes, sister chromatids,
chromatin material, spindle fibers, astral rays, cell plate, cleavage furrow,
haploid (1N), diploid (2N), cell cycle.
Chapter 10:
You should understand the basic differences
between mitosis and meiosis.
You should know what occurs in each phase of the Meiosis
process ( ex. Prophase I, Metaphase II, etc.)
You should know the following terms: synapsis,
crossing-over, chiasmata, gamete, zygote.
Chapter 11:
You should be familiar with Mendel’s First and Second
Laws.
You should know the following terms: genotype, phenotype,
heterozygous, homozygous
(dominant and recessive), punnett square, testcross, allele, codominance, and
incomplete dominance.
You should be able to recognize all genotypic symbols ( ex. HH, Hh, hh ).
You should be able to work through a variety of
monohybrid crosses and interpret the results as far as genotypic and
phenotypic probabilities are concerned. You should also be able to complete
and interpret a dihybrid cross.
