Asexual Reproduction The prefix “A” comes from the Greek language and means “not." "Sex" means "to cross.“

1. In asexual reproduction how many parents are necessary to produce offspring?

2. What might be some benefits to asexual reproduction?

3. How diverse (different) are the offspring of asexual reproduction?

4. Where do the offspring from asexual reproduction receive all of their genetic material?

Sexual Reproduction Sexual reproduction means that two parents combine parts of their genetic material. With sexual reproduction, there is usually a male and a female. The male contributes a copy of half of his genetic material and the female contributes a copy of half of her genetic material.

The “baby” that is born is called the offspring The “baby” that is born is called the offspring. In a very basic way, offspring get half of their traits from each parent. Because of the way the male and female copy their own genetic material and the way they are combined, each offspring is different. Parent (Mom) ½ traits (Dad) Offspring
