Reproduction
Season 1
Episode 9
Sexual reproduction is part of the very definition of what it means to be an animal and as you'll see life has found a variety of methods to pass down genetic information. We explore the differences between sex and gender, and look at sex determination systems, examine how same-sex behavior happens all across the animal kingdom, and live a day-in-the-life of a hermaphroditic clownfish.
