9In the Punnett square shown in Figure 11–1, which of the following is true about the offspring resulting from the cross?
(T=tall and t=short)

- C8
- D16
15Use Figure 11–3 to answer the following question. If a pea plant that is heterozygous for round, yellow peas (RrYy) is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas (RRYy), how many different phenotypes are their offspring expected to show?

- BFruit flies share certain characteristics with pea plants.
- CFruit flies have a long life span.
- DFruit flies take a long time to produce offspring.
18A trait is a specific characteristic that varies from one individual to another.
- ATrue
- BFalse
19True-breeding plants that produced axial flowers were crossed with true-breeding plants that produced terminal flowers. The resulting offspring all produced terminal flowers because the allele for terminal flowers is recessive.

- ATrue
- BFalse
21The principles of probability can explain the numerical results of Mendel’s experiments.

- BFalse
22The probability that a gamete produced by a pea plant heterozygous for stem height (Tt) will contain the recessive allele is 100%.
- ATrue
- BFalse
23A trait in an unidentified plant is controlled by one gene that has two alleles. One allele is dominant over the other. According to Mendel’s principles, one fourth of the offspring made from a cross between two heterozygous plants will show the recessive trait.
- ATrue
- BFalse
24The plants that Gregor Mendel crossed to produce the F1 generation made up the [blank_start]____________________[blank_end] generation.
