Bio Chapter 11 Quiz 1

Each pea-plant gamete has how many alleles for the height gene?

A mule is the result of a cross between a donkey and a horse. A mule is a

If a pea plant has a recessive allele for green peas, it will produce

When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited

When you flip a coin, what is the probability that it will come up tails?

The principles of probability can be used to

A heterozygous tall pea plant is crossed with a short plant. The probability that an F1 plant will be tall is

Organisms that have two identical alleles for a particular trait are said to be

In 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)

If a pea plant’s alleles for height are tt, what is true of its parents?

A tall plant (TT) is crossed with a short plant (tt). If the tall F1 pea plants are allowed to self-pollinate,

What principle states that during gamete formation genes for different traits separate without influencing each other’s inheritance?

The Punnett square in Figure 11–2 shows that the gene for pea shape and the gene for pea color

How many different allele combinations would be found in the gametes produced by a pea plant whose genotype was RrYY?

Use 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?

Gregor Mendel’s principles of genetics apply to

Why did Thomas Hunt Morgan use fruit flies in his studies?

A trait is a specific characteristic that varies from one individual to another.

True-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.

During the formation of gametes in a hybrid tall plant, the tall allele and the short allele stay together.

The principles of probability can explain the numerical results of Mendel’s experiments.

The probability that a gamete produced by a pea plant heterozygous for stem height (Tt) will contain the recessive allele is 100%.

A 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.

The plants that Gregor Mendel crossed to produce the F1 generation made up the [blank_start]____________________[blank_end] generation.

What is the probability of flipping a coin and getting heads 5 times in a row?

In the Punnett square shown in Figure 11–1, the genotypes of the offspring are [blank_start]____________________[blank_end].

If pea plants that are homozygous for round, yellow seeds (RRYY) were crossed with pea plants that are heterozygous for round, yellow seeds (RrYy), the expected phenotype(s) of the offspring would be [blank_start]_________________________[blank_end].

What is the phenotype ratio of the offspring of the plants in the Punnett square in Figure 11–2?

A tall pea plant with yellow seeds is heterozygous for height and seed color (TtYy). This plant is crossed with a pea plant heterozygous for height but homozygous recessive for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds?

Analyze Data In Figure 11–6, what are the different phenotypes of the offspring?

Analyze Data In Figure 11–6, what are the genotypes of the offspring that have black, rough hair?
