Biology CK-12: Mendel's First Experiment

Which of the following statements describes Mendel's first set of experiments?

- Mendel first experimented with just one characteristic of a pea plant at a time. - Mendel started with flower color and crossed two different flower colored plants. - The F1 generation results from cross-pollination of two parent (P) plants contained all purple flowers.

Which phenotypic ratio in the F2 generation was always represented when Mendel let the F1 generation self-pollinate?

3:1

In Mendel's experiments, he cross-pollinated plants in the ________ generation.

P

Assume you are investigating the inheritance of stem length in pea plants. You cross-pollinate a short-stemmed plant with a long-stemmed plant. All of the offspring have long stems. Then, you let the offspring self-pollinate. Describe the stem lengths you would expect to find in the second generation of offspring.

The F2 would have 75% long-stemmed plants and 25% short-stemmed plants.

When Mendel cross-pollinated purple-flowered and white-flowered parent plants, what did he observe?

White-flowered plants disappeared in the F1 generation.

From Mendel's first set of experiments, he concluded that

all of the above are correct

The law of independent assortment states that the two factors (alleles) that control a given trait separate and go to different gametes.

false

The type of cross in Mendel's first experiment is called a dihybrid cross.

false

As shown in Mendel's first experiment, which is a dominant characteristic?

purple flowers

What color(s) of flowers does a pea plant have if it inherits one factor for violet flowers and one factor for white flowers?

violet
