1. Do Now: Mitosis Review
Answer true or false. Use your book on page
9/26/11
Mitosis makes two daughter cells from one parent cell.
In mitosis, a cell divides one time.
Daughter cells have the same DNA as the parent cell.
In interphase, all DNA is copied before mitosis can happen.
In mitosis, the chromosomes split into identical chromatids.
All statements are true!!! Choose one statement and explain why it is true!!!

Make haploid sex cells for sexual reproduction
Regular body cells
What type of cells are made?
Sperm/Egg (sex cells)
Same # as parent cell
(double versions of each chromosome= DIPLOID cell)
How many chromosomes do the daughter cells have?
Half the # as parent cell = HAPLOID cell (1 version of each chromosome)
How many parent cells?
How many divisions? How many daughter cells?
1 parent cell
divides 1 time and makes 2 identical daughter cells
1 parent cell
divides 2 times and
makes 4 different daughter cells

Pairs are separated!

17. Karyotype Review Questions:
Where did these chromosomes come from?
How many chromosomes are there in each human cell?
Is this karyotype of a male or female? How do you know?

18. Karyotype Review Questions ANSWERS:
These are all the chromosomes in a human cell’s nucleus.
Each human cell has the same 46 chromosomes. (23 pairs)
This is of a female because it has 2 X chromosomes and no Y chromosome.

19. Parent Cell is DIPLOID: has a PAIR of each chromosome
Key: Why do the daughter cells need to have HALF the # of chromosomes as the parent cell?
4 Daughter cells are HAPLOID and are all different Sex cells = eggs in female, sperm in male

Sexual Reproduction Summary
Fertilization of Zygote Embryo
Egg and Sperm
3 steps of Sexual Reproduction:
1st step = Meiosis makes haploid sperm in the male parent and haploid egg in the female parent
2nd step = Fertilization of sperm and egg make new DIPLOID cell (zygote)
3rd step = Zygote does mitosis and differentiation MILLIONS of times to make new embryo fetus baby
