Question

Which of the following is an advantage of internal fertilization

Answer 1

Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. Internal fertilization also enhances the fertilization of eggs by a specific male.

Answer 2

The main advantage of internal ferilization is the protection of the fertilized egg.

Step-by-step explanation:

Internal fertilization occurs when the male gamete is deposited inside the female reproductive organ. Mammals are an example of a living being that uses this type of fertilization, however, some types of fish and amphibians also fall into this category.

Internal fertilization has the main advantage of protecting the fertilized egg. For this reason, there is a likelihood that most zygotes produced will survive and form a new organism. This protection is promoted by the reproductive tract of the female, which keeps the fertilized egg inside all or part of its development, preventing the attack of predators or unfavorable environmental factors.
