Sexual Reproduction - nonhuman

What is an advantage of sexual reproduction?

• Allows genetic variation

• Only needs one parent

• Happens very quickly

• Offspring are exact copies of parent

• 224
• 448

By what process are sex cells produced?

• mitosis

• meiosis

• Conjugation

• Fertilization

How does mitosis compare to meiosis?

• Mitosis produces two identical daughter cells while meiosis produces sex cells with half the genetic information.

• Mitosis produces sex cells with half the genetic information, while meiosis produces two identical daughter cells.

• Mitosis occurs only in single celled organisms, while meiosis only occurs in animals.

• Mitosis occurs in animals, while meiosis only occurs in single celled organisms.

In mitosis, the two resulting cells are genetically

• different from the starting cell and identical to each other.

• different from the starting cell and different from each other.

• identical to the starting cell and different from each other.

• identical to the starting cell and identical to each other.
