What is a phenotype

• The genetic make up (code)
• The physical trait

having two of the same genes for the trait (sometimes called purebred).

• hetrozygous
• protein
• chromosome

What does heterozygous mean?

• An organism that has the same genes for a trait (TT or tt)
• An organism that has different genes 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
