Genes that are inherited independently of one another. Example: Pea color and plant height were inherited separately.

• Independent Assortment

• codominance

• dominance

• intermediate inheritance

Mendel developed the basic principles by doing what with peas?

• Using x rays

• Using a microscope to see the DNA

• Guess and check

• Analyzing a large number of offspring

What are the 3 basic principles of heredity?
