Given below are the events in human reproduction. Write them in correct sequential order: Insemination,gametogenesis,fertilisation,parturition,gestation,implantation.
(GAMETOGENESIS, INSEMINATION, FERTILISATION, IMPLANTATION, GESTATION, PARTURITION) The correct sequential order of events in human reproduction is: Gametogenesis $\rightarrow$ Insemination $\rightarrow$ Fertilisation $\rightarrow$ Implantation $\rightarrow$ Gestation $\rightarrow$ Parturition.
Detailed explanation of the processes:
$(1)$ Gametogenesis: The process of formation of gametes (sperms in males and ova in females).
$(2)$ Insemination: The transfer of sperms into the female reproductive tract.
$(3)$ Fertilisation: The fusion of male and female gametes to form a zygote.
$(4)$ Implantation: The attachment of the blastocyst to the uterine wall.
$(5)$ Gestation: The period of embryonic development inside the uterus.
$(6)$ Parturition: The process of delivery of the foetus (childbirth).
