Cell Cycle & Mitosis
Cell Cycle has 4 parts: G1  S  G2  M (with cytokinesis) OR 5 parts: I P M A T
--during interphase, the cell grows, copies DNA, makes organelles, and gets ready to
divide; this is the “growth” period for the cell; G1  S  G2; it is the longest phase
--mitosis only involves BODY CELLS (also known as somatic cells)
--a diploid (2n) cell contains 2 sets of chromosomes-one from mom and one from dad
(46 chromosomes for humans); a haploid (n) cell contains 1 set of chromosomes (23 total for
humans).
--mitosis begins with 1 diploid cell and ends with 2 diploid cells (daughter cells are
identical to each other and parent cell)
--remember what happens in each phase of mitosis:
PROPHASE: nuclear membrane breaks down (in animals 2 centrioles);
chromosomes form; microtubules start to grow
METAPHASE: sister chromatids (joined by centromere) move to the middle
(equator/metaphase plate); spindle forms
ANAPHASE: sister chromatids pull _________ and move to the poles
TELOPHASE: cell starts to divide (cell plate=plant cells; cleavage furrow=animal
cells); nuclear membrane reforms; chromosomes relax into chromatin

3rd Nine Weeks Topics include:
Genetics
Punnet Square
DNA Fingerprinting
When working with Punnett squares you must remember the following terms:
1. Genotype means the _______ ________________-the letters! BB or Bb or bb
2. Phenotype means the ____________ outcome-the traits! Brown hair or black hair
3. Heterozygous = having ______________ alleles; the genotype would be Bb for example.
4. Homozygous = has _______________ alleles; the genotype would be BB or bb for example.
5. Hybrid = same as heterozygous; Bb for example.
6. Pure Dominant = same as homozygous for dominant traits; BB
7. Pure recessive = same as homozygous for recessive traits; bb
Gregor Mendel (1822-1884) is the “Father of ____________________”. His studied ___________ and discovered what
we now have termed Dominant(capital) traits versus recessive(lowercase) traits. He found that those traits that maskedout other traits were the dominant ones. The ones masked-out were recessive. This is known as
________________________. Mendel also founded two principles related to genetics:
A. _______________________________, for any particular trait, the pair of alleles of each parent separate & only one
allele passes from each parent on to an offspring. Which allele in a parent's pair of alleles is inherited is a matter of
chance. We now know that this segregation of alleles occurs during the process of sex cell formation (i.e., meiosis).
B. _______________________________, different pairs of alleles are passed to offspring independently of each other.
The result is that new combinations of genes present in neither parent are possible.
There are different modes/patterns of inheritance (“the exceptions to the complete dominance rule”). The
different modes/patterns of inheritance are:
1. ________________________ = a NEW PHENOTYPE APPEARS-both alleles are expressed and combined-they
blend together; red + white = pink
2. ________________________ = both alleles are equally expressed-each trait shows equally; black + white = black
and white individual-BOTH SHOW EQUALLY!
11
3. ________________________ = more than 2 ALLELES FOR A TRAIT; fur color in rabbits, ABO blood
4. ________________________ = MANY GENES FOR 1 TRAIT; no Punnett square; ex. are height & skin color
5. _______________________ = these are traits that are linked to the SEX CHROMOSOMES-SPECIFICALLY
THE X chromosome. These traits are either present or absent for males. These traits can be carried by females.
