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

• The genetic make up (code)

Dominant alleles are represented by a:

• Male gene
• lowercase letter
• recessive trait
• capital letter

Why are your chromosomes arranged in pairs?

• Because DNA has a double-helix structure.
• Because pairs are able to divide more easily.
• Because you get one from your mother and one from your father.
• Scientists aren't sure.
