What is the P generation in Mendel's experiments?

• The first generation of offspring

• The parent plants

• The second generation of offspring

• Plants grown in pots

When Mendel cross-pollinated purple-flowered and white-flowered parent plants, what was the outcome in the F1 generation?

• All plants had white flowers.

• 75% had purple flowers, 25% had white flowers.

• 50% had purple flowers, 50% had white flowers.

• 100% of plants had purple flowers.

What type of experiment is a monohybrid cross?

• An experiment investigating two characteristics at a time.

• An experiment involving only self-pollination.

• An experiment investigating one characteristic at a time.

• An experiment involving plants from different species.

What was the ratio of purple-flowered to white-flowered plants in the F2 generation of Mendel's first experiment?

• 1:1

• 3:1

• 1:3

• 4:1

Mendel's first law of inheritance is called the:

• Law of Independent Assortment

• Law of Segregation

• Law of Dominance

• Law of Inheritance

According to the Law of Segregation, what happens to the two factors controlling a given characteristic when a parent reproduces?

• They combine.

• They disappear.

• They separate and go to different gametes.

• One completely overrides the other in all generations.
