उत्तर
Humans reproduce sexually.
Explanation:
Humans are sexually reproducing and viviparous. The reproductive events in humans include the formation of gametes (gametogenesis), i.e., sperm in males and ovum in females; the transfer of sperm into the female genital tract (insemination); and the fusion of male and female gametes (fertilisation), leading to the formation of a zygote.
