What organism did Mendel do his famous studies of genetics with? 

• bees
• carrots 
• peas 
• mice

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 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.

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

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

If you cross two heterozygous traits (Rr x Rr), as Mendel did in his second experiment, what ratio will you get between offspring with the dominant and recessive phenotypes

• 1:1
• 2:1
• 3:1
• 4:1

A trait that is not expressed when a dominant allele is present.

• Recessive
• Co-dominant
• Incomplete Dominant
• Dominant

The combination of alleles.

• DNA
• Phenotype
• Genotype
