Chapter 5 Lesson 1 Mendel and His Peas Review

Why did Mendel use cross-pollination in his experiments?

• to speed up self-pollination

• to control which plants pollinated other plants

• to make sure dominant factors were always produced

• to make sure recessive factors were always produced

What did Mendel conclude about inherited traits?

• One factor controls each inherited trait.

• Two factors control each inherited trait.

• Three factors control each inherited trait.

• Multiple factors control each inherited trait.

A true-breeding purple plant and a true-breeding white plant cross-pollinate. The offspring will be _________.

*Purple is the dominant trait

• all purple

• half purple, half white

• 75% purple, 25% white

• 75% white, 25% purple

A genetic factor that blocks another genetic factor is called a(n) _______.

• genetic trait

• heredity trait

• recessive trait

• dominant trait

________ is the study of how traits are passed from parents to offspring.
