What process requires spermatogenesis and oogenesis and results in a zygote?

The correct response is the process of conception, which involves both spermatogenesis and oogenesis. Spermatogenesis is the process through which male gametes, or sperm cells, are produced in the testes, while oogenesis is the process for producing female gametes, or ova, in the ovaries. During conception, a sperm cell fertilizes an ovum, leading to the formation of a zygote—a single cell that results from the combination of genetic material from both parents.

This zygote then carries the complete set of chromosomes needed for the development of an embryo. Following conception, the zygote undergoes subsequent cell divisions and differentiations, which are part of the broader developmental processes involved in embryonic development and fetal development. However, the initiation and essential combination of genetic materials from both sperm and egg during fertilization specifically represent the event termed conception.
