What is a genetic trait?

• A learned behavior

• A characteristic determined by genes

• A temporary condition

• A dietary preference

What is a dominant allele?

• The version of a gene that is always recessive

• The version of a gene that shows up only when paired with another recessive allele

• The version of a gene that shows up in an organism when it also has a recessive version

• The version of a gene that never shows up
