• C. Gametogenesis $\to$ insemination $\to$ fertilization$\to$ $\to$ implantation $\to$ gestation $\to$ parturition
• D. Gestation $\to$ gametogenesis $\to$ insemination $\to$ implantation $\to$ fertilization $\to$ parturition

Answer 1

Answer: (C)

Gametogenesis $\to$ insemination $\to$ fertilization$\to$ $\to$ implantation $\to$ gestation $\to$ parturition

• Gametogenesis is a process of formation of gametes by the germ cells of the reproductive organs. They undergo mitotic and meiotic division to form a functional gamete.
• Insemination is the introduction of sperm into a female animal or plant for the purpose of impregnating or fertilising the female for sexual reproduction.
• Fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.
• Implantation is the very early stage of pregnancy at which the developing embryo adheres to the wall of the uterus.
• Gestation is the process or period of developing inside the womb between conception and birth.
• Parturition is the action of giving birth to young ones.
• Thus, the correct answer is option C.
