Unit 07: Mendel

Who was Gregor Mendel?

• A French Botanist
• A German Physician
• An American Cowboy
• An Austrian Monk

How many traits did Mendel study in his pea plants?

• 1
• 3
• 5
• 7

What is cross pollination?

• When pollen from a flower fertilizes itself or another flower on the same plant
• When pollen from one flower fertilizes a flower on a different plant
• A plant whose offspring share the same traits as the parent
• A plant whose offspring is genetically different from the parent.

What is self-fertilization?

• When pollen from a flower fertilizes itself or another flower on the same plant
• When pollen from one flower fertilizes a flower on a different plant
• A plant whose offspring share the same traits as the parent
• A plant whose offspring is genetically different from the parent.

What is true-breeding?

• When pollen from a flower fertilizes itself or another flower on the same plant
• When pollen from one flower fertilizes a flower on a different plant
• A plant whose offspring share the same traits as the parent
• A plant whose offspring is genetically different from the parent.

What did Gregor Mendel do in his first experiment?

• Self-Pollinated two pea plants
• Self-Pollinated two true-breeding pea plants
• Cross-pollinated two pea plants
• Cross pollinated two true-breeding pea plants

If Mendel's first experiment involved cross-pollinated a true-breeding round pea plant and a true-breeding wrinkled pea plant, what would the genotypes of the parents have to be?

• RR x Rr
• Rr x Rr
• rr x rr
• RR x rr

What did Gregor Mendel discovery in the results of his first experiment?

• Only the dominant trait appeared!
• The offspring were all different!
• Only the recessive trait appeared!
• The plants were more healthy

What did Gregor Mendel do in his second experiment?

• Allowed the first generation to self-pollinate
• Allowed the first generation to cross-pollinate
• Allowed the first generation to become true-breeding
• Allowed the first generation to both self-and-cross pollinate

Originally, Mendel crossed two true breeding plants (RR x rr) for Round and Wrinkled peas. What is the genotype(s) of the offspring that he then allowed to self-pollinate in the first generation?

• RR x Rr
• Rr x Rr
• rr x RR
• rr x Rr
