1. C
2. Nuclei: gene/DNA
3. They are still in the form of loosely packed chromatin fibers
4. B
5. prophase, telophase
6. a. 1,1 b. 1, 2 c. 2, 4 d. 2n, n e. aligns in the middle, pairs in the middle f. identical, unique g.
asexual reproduction, gamete formation
7. 39
8. Prophase II or metaphase II, that is when you can see an even number of chromatids
9. benign, malignant
10. 16
11.
Nondisjunction creates the same number of gametes with a copy of the 3 or 16
chromosome. Extra copies of these chromosomes can be very dangerous and fatal to the
person that has them.
12. Information flow- genetic instructions are passed from one generation to another
13. Interactions within biological systems- the actions of different proteins each contribute to
cell division
14. Relationship of structure to function- the loose or tight wound chromosome region allows
insight to what genes are being used
15.
The mules 63 chromosomes divide into two cells that both contain 63 in mitosis. Because in
meiosis it created four different chromosomes, but because it is an odd number it cannot be
divided into equal parts so meiosis cannot occur.
