• 8

• 16

• 32

• 64

A zygote is formed during a process called

• They have genes that are in the same order.

Which statement best describe Mendel’s experiments?

• He began with hybrid plants

• He controlled pollination

• He observed only one generation

• He used plants that reproduced slowly

Before Mendel’s discoveries, which statement described how people believed traits were inherited?

• Parental traits blend like colors of paint to produce offspring

• Parental traits have no effect on their offspring

What is heredity?

• The study of how traits are passed from parent to offspring

• The study of DNA
