Reproduction & Heredity

What is a phenotype?

• the expression of a trait; physical appearance.
• the genetic makeup of an individual
• an organism that has the same genes for a trait (ex. TT or tt)
• the passing of traits from parent to offspring

What does heterozygous mean?

• an organism that has the same alleles for a trait (ex. TT or tt)
• an organism that has different alleles for a trait (Tt)
• When neither gene is fully dominant; offspring is a mixture of both
• the different forms of a trait (hair color: brown, blonde, red, etc.
