BIO 1020 POPULATION GENETICS POST LAB QUESTIONS –AUBURN UNIVERSITYPost-Questions and Data for the Population Genetics/Hardy-Weinberg Lab
Attention: These questions will be answered from your Population Genetics/Hardy-Weinberg Manuel.
1. Which of the following describes the differential selection rate in the reproduction of different
phenotypes resulting from the interactions of the organisms with their enivornment?
a. gene pool
b. allelic frequency
c. genetic equilibrium
d. theoretical genotype frequency
e. natural selection
2. Who's work focused on hybridization experiments using pea plants where organisms of one type are
bred to organisms of another type?
a. Charles Darwin
b. Gregor Mendel
c. H.B.D. Kettlewell
d. Carl Linnaeus
e. Alfred Russel Wallace
3. Each organism has two versions of each gene, one inherited from each parent. What are these versions
called?
a. alleles
b. genotypes
c. phenotypes
d. stochastic effect
e. heterozygous
4. If a flower receives a yellow, dominant allele from one parent, and a purple, recessive allele from the
other parent, the flower will be yellow. What term best describes this combination of alleles?
, a. genotype
b. phenotype
c. heterozygous
d. homozygous
e. genetic equilibrium
5. If "R" represents the dominant gene for the phenotype for brown eyes, and "r" represents the recessive
gene for the phenotype for green eyes, what combination of these letters represents a person with green
eyes?
a. Rr
b. rR
c. RR
d. rr
e. r
6. Explain the difference between genotype and phenotype.
The combination of the alleles is the genotype and the specific trait expressed by the genotype is the
organism’s phenotype.
7. Which of the following is NOT a requirement of the Hardy-Weinberg Principle?
a. there is no genetic mutation
b. there is no immigration or emigration
c. the population is infinitely large
d. there is natural selection present
e. there is completely random mating within the population
8. Which of the following is NOT an example of natural selection?
a. one flower produces more nectar and attracts more bees than the neighboring flowers
