Describe the process of developing zygote from conception to implantation
What will be an ideal response?
Within 36 hours after conception, the zygote divides into two cells. It then divides repeatedly as it undergoes its three-to-four day journey to the uterus. Within another 36 hours, the zygote has become 32 cells. The mass of dividing cells wanders about the uterus for another 3 to 4 days before it begins to implant in the uterine wall. Implantation takes another week or so.
