1) What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants?
A) There is considerable genetic variation in garden peas.
B) Traits are inherited in discrete units, and are not the results of "blending."
C) Recessive genes occur more frequently in the F1 generation than do dominant ones.
D) Genes are composed of DNA.
E) An organism that is homozygous for many recessive traits is at a disadvantage.
2) How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE? Write down the gametes
3) Why did Mendel continue some of his experiments to the F2 or F3 generation?
A) to obtain a larger number of offspring on which to base statistics
B) to observe whether or not a recessive trait would reappear
C) to observe whether or not the dominant trait would reappear
D) to distinguish which alleles were segregating
E) to be able to describe the frequency of recombination
4)Two plants are crossed, resulting in offspring with a 3:1 ratio for a particular trait. What does this suggest?
5) The fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment. What does this suggest about the seven traits studied by Mendel?
6) In the cross AaBbCc × AaBbCc, what is the probability of producing the genotype AABBCC
7) Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the progeny will be expected to phenotypically resemble the first parent?
8) Which of the following is the best statement of the use of the addition rule of probability?
A) the probability that two or more independent events will both occur
B) the probability that two or more independent events will both occur in the offspring of one set of parents
C) the probability that either one of two independent events will occur
D) the probability of producing two or more heterozygous
