Characteristics of Sexual Reproduction

Human reproduction is sexual. This means that it's necessary for two individuals of different sexes to take part.

1. Each sex produces a different type of sex cell or gamete.
2. Fertilization is internal; it takes place inside the female reproductive system.
3. We are viviparous; the fetus grows in the mother's womb.
4. We are sexually dimorphic. This means that males and females have physical differences. This happens in many species.
