Asexual and Sexual Reproduction (7.5.1)Organisms have two ways of reproduction: asexually (one parent) and sexually (two parents). Both have their benefits and dangers.

Asexual reproduction (having one parent from which 100% of the DNA is transferred) includes fission (bacteria), mitosis (eukaryotes), regeneration, potatoes and banana suckers. It's fast, no need to find a mate, and the good genes are guaranteed to be passed on. However, the bad genes are also passed on, and the lack of genetic diversity becomes a problem (more about this as we learn about bananas).

Sexual reproduction (having two parents from which 50% of the DNA is transferred from each) includes an egg cell (mother) and a sperm cell (father). We'll cover fertilization, parrotfish populations, and meiosis. Genetic diversity is ensured, but time and energy is needed to find a mate.
