Hardy Weinberg Equilibrium
Question #1:
 In a population of
dominant and recessive
alleles for the trait color
seen in Snapdragon
flowers, the dominant
allele frequency is 0.7.
What would the recessive
allele frequency be?
 a. recessive allele is 0.3
 b . recessive allele is 0.93
 c. recessive allele is 70%
 d. recessive allele is 0.2
Question #2:
 What would be the correct
way to rearrange P + q =
1.00, to solve for the
recessive allele frequency?
 A. P = q = 1.00
 B. P = 1 - q
 C. q = 1 - P
 D. It is impossible to solve
recessive allele frequencies
using this formula

Question #3:
 In a population of 10 mice
that display brown and
white coat color, what
would be the recessive and
dominant allele frequency,
if 4 display the recessive
phenotype of brown?
 a. Dominant 0.3 and
Recessive 0.7
 b. Dominant 0.4 and
Recessive 0.6
 c. Dominant 0.6 and
Recessive 0.4
 d. None of the above are
correct
Question #4:
 When solving for
genotypic
frequencies, which
of the following
statements is false?
 a. The formula P2 + 2Pq
+ q2 = 1.00 can be used
 b. A cross-multiplication
table can be used
 c. q2 represents the
homozygyous recessive
genotypic frequency
 d. P2 from the equation
would represent the
homozygous recessive
genotype
Question #5:
 A large population of
laboratory animals has been
allowed to breed randomly
for a number of generations.
After several generations,
36% of the animals display a
recessive trait (aa), the same
percentage as at the
beginning of the breeding
program. The rest of the
animals show the dominant
phenotype, with
heterozygotes
indistinguishable from the
homozygous dominants.
 What are the dominant and




recessive allele frequencies in
the population?
a. P = 0.4 & q = 0.60
b. P = 0.40 & q = 0.30
c. P = 0.18 & q = 0.72
d. P = 0.80 & q = 0.20
Question #6:
 The allele for a hitchhiker's
thumb is dominant over a
straight thumb. In a
population of 1000
individuals, 510 show the
dominant phenotype. How
many individuals would
you expect for each of the
three possible genotypes
for this trait?
 a. PP = 9%, Pq = 49%,
qq = 42%
 b. PP= 42%, Pq = 9%, qq
= 49%
 c. PP = 49%, Pq = 42, qq
= 9%
 d. PP = 9%, Pq = 42%,
qq = 49%
Question #7:
 If 98 out of 200 individuals
 a. 49%
in a population express the
recessive phenotype, what
percent of the population
are homozygous dominant?
 b. 70%
 c. 30%
 d. 42%
 e. 9%
Question 8:
 If 98 out of 200 individuals
 a. 49%
in a population express the
recessive phenotype, what
percent of the population
are heterozygotes?
 b. 70%
 c. 30%
 d. 42%
 e. 9%
Question 9: the Science of classification is called
and was developed by _________:
 A. Taxodermy-Linnaeus
 B. taxonomy-leonardo da vinci
 C. Namology-Linnaeus
 D. taxonomy- Linnaeus
 E. none of them
Question 10: Which is the correct
sequence:
 A. phylum-domain-kingdom-order-class
 B. Kingdom-phylum-order-class-genus
 C. Kingdom-phylum-class-order-family
 D. kingdom-phylum-family-order-class
 E. none of them
