Mendel and His Peas

Pollen from a plant fertilizes the eggs of the same plant in this process

• cross-pollination
• cross-breeding
• self-pollination
• self-breeding

When parents with different traits are cross-bred, a trait that reappears in the second generation after disappearing in the first generation is a

• dominant trait
• recessive trait
• true-breeding trait
• characteristic

When a first-generation plant self-pollinates, what is the ratio of dominant to recessive traits in the second-generation plants?

• 1:3
• 3:1
• 1:4
• 4:1

The passing of genetic traits from parent to offspring is called

• cross-pollination
• cross-breeding
• heredity
• genetics
