List in order the phases of mitosis.
Something that is diploid, __n, has ____ set of chromosomes.

Something that is haploid, __n, has ____ set of chromosomes.
(answers 1,2, full, or half.)
 ________Condenses and compacts to form chromosomes.

T / F
There are three types of cellular division: Mitosis I, Mitosis
II, and Meiosis.

How many chromatids are present in a Human cell at metaphase in
mitosis? [Hint: Draw a simple picture of an organism whose diploid
number is 4, figure out how many chromatids that organism would have at
metaphase in mitosis and then just apply that relationship to a Human
cell.]
a) 23
b) 46
c) 72
d) 92

During Meiosis there are ______ rounds of DNA replication and ______
rounds of cellular division.
a) 1, 2
b) 2, 3
c) 2, 1
d) 4, 2

The skin and brain all develop from which embryonic germ layer?
_____________

What type of cellular division occurs when you cut your hand and the cells
around the cut divide to heal the wound? ______________

True or False
T / F
The chromosomes inherited from the mother MUST remain
together following Meiosis I.
T / F
For cells undergoing Meiosis, DNA is only replicated before Meiosis
I, it is not replicated
again before Meiosis II.
T / F
Crossing over occurs between homologous chromosomes, not
between sister chromatids.
T / F
Crossing over is observed in both Mitosis and Meiosis.
T / F
cells.
Meiosis is cellular division that creates haploid cells from diploid
T / F
During metaphase I of Mitosis, tetrads can be found.

A _______________ is a picture that displays chromosomes by
homologous pairs. One use of this picture is the diagnosis of certain
problems with a fetus during pregnancy.

A couple decides to have a baby. What is the minimum number of
genetically different possible offspring this couple can have solely based
on the independent assortment of chromosomes in Meiosis without taking
crossing over into consideration? Show the one mathematical step you
used to determine your answer to receive full credit.
a) 2184
e) 292
b) 246
c) 268
d) 212
