Two brown-eyed parents (Bb and Bb) have a baby. What is the chance the baby is blue-eyed? *(make a Punnett square to see.)

• 0 %

• 25%

• 50%

• 75%

What is one advantage of sexual reproduction?

• offspring are identical to parents

• offspring are resistant to viruses

• offspring are born live, rather thna from eggs

• biodiversity- offspring inherit a wider variety of genetic information

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

Sex cells are produced through the process of

• mitosis
