Which of the following indicates the correct reproductive sequence?

64% Answer Correctly

ovum → fetus → zygote

ovum → zygote → fetus

none of these are correct

zygote → ovum → fetus
Solution

During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina.

The zygote then may implant in the uterus and eventually develop into a fetus.
