Question 2: In snapdragon plants, flower color is determined by one gene with two incompletely dominant alleles. RR plants have red flowers RR' plants have pink flowersR'R' plants have white flowers In a population of snapdragon plants, we find 4444 red-flowered plants, 4444 pink-flowered plants, and 1111 white-flowered plants. What is the frequency of the R allele in this population?
a. 0.33
b. 0.25
c. 0.50
d. 0.67
e. 0.75
Question 3: Which of the following are features of Mendel's approach to studying inheritance?
a. Using traits that only appear in two distinct forms
b. Analyzing data quantitatively
c. Establishing true-breeding lines
d. Simplifying the problem
e. Using an organism in which he could control all matings
Question 4: What was the dominant scientific theory of inheritance when Mendel started his research?
a. Blending inheritance
b. Traits of offspring are determined by the mother
c. Traits of offspring are determined by the father
d. Particulate inheritance
e. DNA is the genetic material
Question 5: In fruit flies, red eyes are dominant to white eyes and normal wings are dominant to curled wings.
We cross a true-breeding red-eyed, curled-wing fruit fly with a true-breeding white-eyed, normal-winged fruit fly, and then inbreed their offspring, what proportion of the F2 offspring will have red eyes and curled wings?
a. 1/9
b. 1/4
c. 1/16
d. 3/16
e. 9/16.
