100
B is the dominant allele (brown eyes) and b is the recessive allele (blue eyes). What color eyes would a heterozygous individual possess phenotypically?
Bb, Brown
100
p and q: which represents the dominant allele, and which represents the recessive allele?
p= dom q= rec
100
If p squared is .09, how would one find p?

100
A cardiac muscle is voluntary/involuntary?
involuntary
200
_________ selection is selective breeding of domesticated plants and animals
Artificial
200
Two parents mate (both heterozygous for eye color Bb). Bb x Bb. Is this a monohybrid cross or dihybrid?
Monohybrid, only one trait is being examined.
200
A large population of rabbits (65% white are white rabbits, 35% are black rabbits) that mate randomly live in a habitat in which there is always snow on the ground. Coyotes prey on the black rabbits predominantly bc they don't blend in well. Does this population satisfy all 5 HW conditions? Yes, No, or insufficient information?
No, natural selection is occurring.
200
In order to successfully complete a test cross, the individual must be mated with an individual of what genotype? Homozygous dominant, heterozygous, or homozygous recessive?
homozygous recessive
200
Name one reason for examining pedigrees.
To determine genetic disorders, and likelihood of offspring genotypes/phenotypes.
300
The ______ effect occurs when a few individuals colonize a new habitat
founder
300
Two parent flowers mate, one red (RR) and one white (rr). Assuming incomplete dominance, what color will all of the F1 offspring be?
pink
300
What are the two HW equations?
p+q=1, p2+2pq+q2=1
300
________ genes are located close together on the same chromosome and tend to be inherited together.
Linked
300
What is the difference between microevolution and macroevolution?
microevolution is small scale (allele) and macro is large scale (population changes)
400
Alternating waves of contraction and relaxation by smooth muscle
Peristalsis
400

Tg TG tG tg
400
If a total population of 500 contains 110 homozygous recessive individuals, what is q squared?
110/500=.22 or 22%

What is the definition of Pleiorophy?
One gene influencing many characteristics
500
On the board, cross two flies. XRXr and XRY. This is an example of an X-linked trait. "R" is the dominant allele that represents red eyes. "r" is the recessive allele that represents white eyes. What is the probability of having a white eyed offspring?
25%
500
Name the 5 conditions for equilibrium according to the HW principle. 100 pts for each condition
1. large population 2. random mating 3. no migration 4. no mutation 5. no natural selection

Something that eradicates the majority of a population...
