The period of the zygote begins with conception and ends with implantation into the uterine wall, which takes about two weeks.

Option B is incorrect because the formation of major body systems occurs during embryonic development, not during the period of the zygote. Option D is incorrect because ossification occurs during fetal development, not during the period of the zygote.
