What type of reproduction involves the fusion of male and female gametes?

The type of reproduction that involves the fusion of male and female gametes is called sexual reproduction. Here are the steps:

1. Production of Gametes: The process begins with the production of gametes, or sex cells, in the male and female reproductive organs. In males, these are sperm cells, and in females, these are egg cells.

2. Fertilization: The next step is fertilization, which is the fusion of the male and female gametes. This usually occurs in the female's body. The sperm cell from the male penetrates the egg cell from the female, combining their genetic material.

3. Development of Zygote: The fertilized egg, now called a zygote, starts to divide and grow into an embryo. This process is called embryogenesis.

4. Growth and Development: The embryo continues to grow and develop, eventually forming all the structures and organs of a new individual.

5. Birth: Finally, the new individual is born or hatched, depending on the species.

This type of reproduction results in offspring that are genetically different from both parents, which contributes to genetic diversity in a population.
