Question

A hypothetical population ofcats has two alleles, T^{L}
and T^{S}, for a gene that codes for tail length. The
allele frequency of T^{L} is 0.7 and the allele frequency
of T^{S} is 0.3.

- T
^{L}T^{L}individuals have long tails. - T
^{L}T^{S}individuals have medium tails. - T
^{S}T^{S}individuals have short tails.

The equation for Hardy-Weinberg equilibrium states that at a
locus with two alleles, as in this cat population, the three
genotypes will occur in specific proportions, described by the
equation p^{2} + 2pq + q^{2} = 1.

What are the expected genotype frequencies for
T^{L}T^{L}, T^{L}T^{S}, and
T^{S}T^{S}, respectively?

In a Hardy-Weinberg population with two alleles, T and
t, that are in equilibrium, the frequency of the allele
t is 0.3.
Therefore [ Select ]
["p^2",
"p", "q", "q^2"] = 0.3
What is the percentage of the population that
is Homozygous dominant (TT) for this
allele? [ Select ]
["70", "0.7", "49", "0.49"]

43. A gene has two alleles a and b. In the
gene pool, the a allele accounts for 70 percent of the
alleles at this locus. If the population is in Hardy-Weinberg
equilibrium, what percentage of the population is heterozygotes
with respect to this locus?
A. 21 percent
B. 30 percent
C. 49 percent
D. 70 percent

1. There are two alleles at a locus: A and P. Assume these two
alleles are in Hardy-Weinberg equilibrium. Assume also that Allele
P has a frequency of exactly 1% in the population. Given this
information, what is the frequency of AP heterozygotes in the
population?
2. You are studying an allele A that governs parasite resistance
in a large population of rabbits.
You observe that different combinations of A and a produce
phenotypes that have different fitnesses due to...

Given a single genetic locus with two alleles: A1,
which occurs at a frequency 0.75, and A2, which occurs
at a frequency of 0.25, how may individuals of genotype
A2A2 do you expect in a population of 600
individuals at Hardy-Weinberg equilibrium?

Consider a racoon population that exhibits variation at the G
locus, which has two possible alleles: G1 and
G2. The population starts out at Hardy Weinberg
Equilibrium and the frequency of the G1 allele in the
original population is 0.3. The relative fitness of each genotype
during this generation is listed below. Use information to answer
the following questions.
w11 = 0.8
w12 = 1.0
w22 = 0.5
Calculate the average fitness for the population.
Calculate the genotype frequencies in...

A fruit fly population has a gene with two alleles,
A1 and A2. Tests show that 60% of the gametes
produced in the population contain the A1 allele. If the
population is in Hardy-Weinberg equilibrium, what proportion of the
flies carry both A1 and A2?
0.70
d. 0.48
0.36
e. 0.24
0.09

Coat colour in a population of rodent is caused by a single
locus on the X chromosome where white is dominant over black.
Assuming this population is in Hardy-Weinberg equilibrium, what is
the frequency of females that have patches of both black and white
fur given that the frequency of black individuals is 0.3?
a) 0.70
b) 0.50
c) 0.01
d) 0.84
e) 0.42

A gene in a randomly-mating population has two alleles (A,a),
and the allele frequency of A is 0.65. Calculate the frequency of
homozygous recessive individuals (aa) in the population.

Let A and a be the alleles at a locus l in a population evolving
with inﬁnite, non-overlapping
generations. Assume that the probability an AA child survives to
reproductive maturity is
0.8; for genotype Aa assume this probability is 0.6 and for
genotype aa it is 0.7. Let fA(t)
denote the frequency of A among the newborns of generation t. The
population at birth in
generation 0 is in Hardy-Weinberg equilibrium with fA(0)
= 0.4.
(a) What is the probability...

In a bird species, the shape of the beak is encoded by a locus
with two 2 co-dominant alleles Na and Nz. Na gives long beak in
double dose, while individuals who are homozygous for Nz have short
beak.
In a population, the following genotype frequencies were
observed:
Na Na = 0.5
Na Nz = 0.3
Nz Nz = 0.2
a) Assume a total of 600 individuals in the population. Set up a
hypothesis and use an x2 test to...
