Question #1
What can be learned from studying a population through time?

D.   invasive to a particular region or habitat.
Question #13
mtDNA is found ________ and is ________.

Question #14
The number of different chromosomes in a plant or animal
A.   varies between body cells (e.g., liver cells have more than intestinal cells).
B.   determines how evolved the organism is (potatoes have only five, but camels have seventy).
C.   reduces over the animal’s lifetime, causing aging.
D.   is the same in every cell with a nucleus; it is homoplasmic.
Question #15
Haplotypes are a group of alleles that
A.   does not pass on for many generations.
B.   is not likely to recombine during crossovers.
C.   comes from one parent only.

Question #17
Most cells in the human body contain a nucleus,
A.   each containing a full copy of the organism’s DNA.
B.   containing exactly one half of the organism’s DNA.
