• Punnett Square
• Phenotype
• Genotype
• Dominant allele

What does a Punnett Square help you do?

• Determine the ratio of phenotypes
• Determine the ratio of genotypes
• Predict possible traits the offspring will have
• All of the above

A phenotype is the...

• letter combination
• dominant gene
• recessive gene
• physical appearance

One reason for Mendel's success with genetic studies of peas was that he

• used only hybrid pea plants
• used peas with large chromosomes
• studied large numbers of offspring
• discovered the sources of variation in peas
