Why were peas an excellent test subject for Gregor Mendel's experiments on inheritance?

• They have a long growth cycle.

• They can self-pollinate, cross fertilize, and have several traits that only have two forms.

• They require complex care and maintenance.

• They have a single trait that comes in many forms.

How many traits of the pea plant did Gregor study in his experiments?

• Five

• Six

• Seven

• Eight

What did Gregor call the plants that were part of the first generation of true-breeding plants?

• F1 generation

• F2 generation

• P generation

• G generation

How was the second generation of plants (F1) produced according to Mendel's experiments?

• By self-pollinating two P generation plants

• By breeding two different true-breeding P plants

• By self-pollinating two F2 generation plants

• By breeding two different F2 generation plants

What method did Gregor use to produce the third generation of plants (F2)?

• By breeding two different F1 generation plants

• By self-pollinating two F1 generation plants

• By self-pollinating two P generation plants

• By breeding two different P generation plants

What did Mendel find about the F1 generation in his experiments with pea plants?

• The F1 generation showed a mix of traits from both parents.

• The F1 generation all produced the same trait.

• The F1 generation had no discernible traits.

• The F1 generation showed new traits not found in either parent.

Why did all the F1 plants have purple flowers when Mendel bred a P plant with a purple flower with a P plant with a white flower?

• Because the white flower is the dominant trait.

• Because the purple flower is the recessive trait.

• Because the purple flower is the dominant trait.

• Because Mendel used only purple-flowered plants.

What is a Punnett square used to show?

• The results of a chemical reaction

• The potential genotypes of offspring from a genetic cross

• The physical characteristics of an organism

• The lifecycle of a plant
