8Organisms that have two identical alleles for a particular trait are said to be
- Adominent
- Bheteorzygous
- Chybrid

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)
- AAll are expected to be short.
- BAll are expected to be tall.
- CAbout three fourths are expected to be tall.
- DAbout half are expected to be short.
10If a pea plant’s alleles for height are tt, what is true of its parents?
- ABoth parents were short
- BBoth parents contributed a recessive allele.
- CBoth parents were tall
- DBoth parents contributed a dominant allele.
11A tall plant (TT) is crossed with a short plant (tt). If the tall F1 pea plants are allowed to self-pollinate,
- Aall of the offsprings will be tall
- Bthe offspring can be either tall or short
- Cthe offspring will be of medium height.
- Dall of the offsprings will be short
12What principle states that during gamete formation genes for different traits separate without influencing each other’s inheritance?

- Bprinciple of segregation
- Cprinciple of independent assortment
- Dprinciple of dominance
13The Punnett square in Figure 11–2 shows that the gene for pea shape and the gene for pea color
- Aare linked.
- Bare always homozygous.
- Chave the same alleles.
- Dassort independently.
14How many different allele combinations would be found in the gametes produced by a pea plant whose genotype was RrYY?
- A2
- B4
- 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?
- A8
- B2
- C16
- D4
16Gregor Mendel’s principles of genetics apply to

17Why did Thomas Hunt Morgan use fruit flies in his studies?
- AFruit flies produce a large number of offspring.
- 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.
- AVerdadero
- BFalso
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.
- AVerdadero
- BFalso
20During the formation of gametes in a hybrid tall plant, the tall allele and the short allele stay together.
- AVerdadero
- BFalso
21The principles of probability can explain the numerical results of Mendel’s experiments.
- AVerdadero
- BFalso
22The probability that a gamete produced by a pea plant heterozygous for stem height (Tt) will contain the recessive allele is 100%.
- AVerdadero
- BFalso
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.
- AVerdadero
- BFalso
24The plants that Gregor Mendel crossed to produce the F1 generation made up the [blank_start]____________________[blank_end] generation.
- AP
