Gregor Mendel

What is his role in genetics? S5L2: Students will recognize that offspring can resemble parents in learned behaviors and inherited traits.

How are traits passed from parents to offspring?

A genetic experiment with pea plants answers the question.

What were the results of Mendel's experiments with pea plants?

• he bred short and tall pea plants
• the first generation were all tall
• the second generation 3 were

tall and 1 was short

What conclusions did he draw from his experiments?

• 2 factors determine a trait (genes)
• 1 gene is passed from each parent
• there's a strong gene called dominant
• there's a weaker gene called recessive
• factors can skip a generation
• these conclusions apply to all organisms

How can scientists predict traits

• f offspring from a set of parents?
