Multiple Choice

What would be the gamete types of an individual with a genotype AaBB?

• Aa and BB

• AB and aB

• A, a, and B

• AaBB

Multiple Choice

How many possible different phenotypes could there be in a dihybrid cross between two heterozygous parents for both traits?

• 16

Multiple Choice

Mendel's Principle (Law) of _______ tells us that alleles separate during gamete formation and alleles from one trait/gene do not influence the passing on of alleles from another trait/gene.

• Segregation
