When an offspring has the recessive form of a trait, what does that mean about the parents?

• Both parents must have 2 dominant alleles

• one of the parents has 2 dominant alleles and the other parent has 2 recessive alleles

What does heterozygous mean?

• the different forms of a trait (red hair, brown hair, etc)

• when an organism has two of the same alleles for a trait (ex. RR)

• when an organism has two different alleles for a trait (ex.Tt)

• neither gene is dominant over the other and a blend of both traits appear in the offspring

What does homozygous mean?

• when an offpsring has 2 of the same alleles for a trait

• when an offspring has 2 different allels for a trait

• when the offspring only has 1 allele for a trait

• when the offspring has 2 alleles for a trait
