Question

Which of the following is an advantage of internal fertilization

Answer 1

Answer and Explanation:

Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth .  The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting . Even though fewer offspring are produced through this method, their survival rate is higher.
