Question

QUESTION 2 Crossing true breeding dark-coated sheep with true breeding light-coated sheep always results in 100% dark-coated offspring. You are screening a population of 300 Soay sheep for coat color, and you count 224 dark sheep and 76 light sheep. What is the genotype frequency of the homozygous recessive sheep for TYRP1 gene if the population is in Hardy-Weinberg equilibrium? a. 0.747 b. 0.253 c. 0.864 d. 0.503 1 points

QUESTION 3 In the same population, if it is under Hardy-Weinberg equilibrium, how many individuals do you expect to be heterozygous at TYRP1? a. 150 b. 0.500 c. 261 d. 75 1 points

QUESTION 4 Rabbit’s ears can be either short (dominant) or floppy (recessive). If a population of rabbits in Hardy-Weinberg equilibrium has 250 short eared rabbits and 100 floppy eared rabbits, what is the allele frequency of the “short” allele? a. 0.714 b. 0.465 c. 0.845 d. 0.535 1 points

QUESTION 5 You are observing the suit (clubs, diamonds, hearts, or spades) of a randomly drawn card from a deck. What is the degree(s) of freedom if you were to perform the Chi-square test on the expected and observed outcome of the suits of the cards? a. 1 b. 0 c. 3 d. 4 1 points

QUESTION 6 You perform a Chi-square test for gene X and find the p-value to be between 0.05 and 0.01. What can you say with 95% certainty about this population? a. This population is in Hardy-Weinberg equilibrium at the X locus: gene X is influenced by at least one force of evolution. b. This population is in Hardy-Weinberg equilibrium at the X locus: gene X is not influenced by any forces of evolution. c. This population is not in Hardy-Weinberg equilibrium at the X locus: gene X is influenced by at least one force of evolution. d. This population is not in Hardy-Weinberg equilibrium at the X locus: gene X is not influenced by any forces of evolution.

Answer #1

1) Rabbit’s ears can be either short (dominant) or floppy
(recessive). If a population of rabbits in Hardy-Weinberg
equilibrium has 250 short eared rabbits and 100 floppy eared
rabbits, what is the allele frequency of the “short” allele?
A.0.714
B.0.465
C.0.845
D.0.535
2)You are observing the suit (clubs, diamonds, hearts, or
spades) of a randomly drawn card from a deck. What is the degree(s)
of freedom if you were to perform the Chi-square test on the
expected and observed outcome...

1.) What gives rise to different variations of traits within a
species?
a.
Different alleles of a gene
b.
Varying distances between genes
c.
Natural selection
D. None of the above
2.) Crossing true breeding dark-coated sheep with true breeding

Complete the following 10 questions. To get complete credit, you
must show your work for calculations and type the correct answers
in the yellow highlighted boxes. Round final calculations to two
digits. Partial credit will be given for using the correct
equations, but getting the wrong answer. Minimal credit (a quarter
of possible points) will be given for providing answers with no
equations. Even if you only answer a few of the questions, submit
the assignment on time. Material covered...

Part I. You are investigating the evolution of
cuticle color in a scarab beetle inhabiting a desert. Coloration is
determined by a single gene A with two alleles:
A1 codes for a dark brown
color, and A2 codes for a grey
color. Since the alleles are incompletely dominant,
heterozygotes are tan. Therefore
the heterozygotes are almost invisible on the sandy desert floor,
while homozygotes are more visible and thus more susceptible to
predation.
Questions: (a) Based on the given information,...

) Imagine that you are a grad student in
Biological Anthropology, and you travel to the land of
“Jenesaiquoivia” to study Jenesaiquoivian genetics. [Footnote
1]
You notice that 9 out of every 100 people in your study group have
blue eyes. The rest of the population have brown eyes. You know
that the brown eyes allele is dominant, and blue eyes is recessive.
[2]
Construct the Hardy-Weinberg equation for that population. You
know that q2=.09 (9%) so p2 plus 2pq...
