Question 2

Blending hypothesis

Answer 2

Question 3

Characteristics

Answer 3

An inherited feature (example: seed shape)

Question 4

Trait

Answer 4

Question 5

Closed structure

Answer 5

Pea flower permits self-fertilization and once the anther is removed the closed structure of the pea flower makes it easy to control the origin of pollen to allow the experimenter to cross-pollinate.

Question 6

Presence of distinctive traits

Answer 6

Question 7

Rapid reproductive cycle

Occurs when pollen is transferred from the anthers to the stigma of the same flower on the same plant.

Question 9

Cross-pollination

Answer 9

When pollen is removed from one plant and is transferred to another plant of the same species.
