• Heredity

• Genetics

• Inheritance

• Biology

What is heredity?

• The passing of traits from parents to offspring

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

What species of plants did Mendel use?

• Sunflowers

• Cacti

• Bean plants

• Pea plants

Why did Mendel use that species of plants?

• They reproduce fast, have easily observed traits and are easy to manipulate.

• They reproduce fast, have easily observed traits and can't be manipulate.

• They reproduce slowly, have easily observed traits and are easy to manipulate.

• They reproduce fast, have a few observed traits and are easy to manipulate.

In this type of crosses, the offspring always have traits that match with the parents:

• Cross-pollination

• True-breeding

In this type of crosses, you are able to select which plants pollinate other plants:

• Cross-pollination

• True-breeding

• This can't occur

In the first generation of Mendel's experiment all the plants expressed the traits of their parents:

• True

• False

In the second generation of Mendel's experiment, most of the flowers were purple but some white also appeared:

• True

• False

A genetic factor that is blocked by the presence of another factor:

• Dominant trait

• Recessive trait
