Question
What can be inferred about the process of foetus formation?a. The development of embryo into foetus requires the attachment of embryo to the wall of theuterus.b. The development of embryo into foetus starts with the zygote anchoring itself to the walls ofthe oviduct.c. The development of embryo into foetus does not involve fusion of gametes.d. The development of embryo into foetus begins with the process of ovulation where a zygoteis released from the ovary
Solution
The process of fetus formation can be inferred from the following points:
a. The development of an embryo into a fetus does indeed require the attachment of the embryo to the wall of the uterus. This process is known as implantation and it usually occurs about a week after fertilization.
b. The development of an embryo into a fetus does not start with the zygote anchoring itself to the walls of the oviduct. The zygote actually travels down the fallopian tube and into the uterus where it implants itself into the uterine wall.
c. The development of an embryo into a fetus absolutely involves the fusion of gametes. The fusion of a sperm cell (male gamete) and an egg cell (female gamete) results in a zygote, which then begins to divide and grow into an embryo.
d. The development of an embryo into a fetus does not begin with the process of ovulation where a zygote is released from the ovary. Ovulation involves the release of an egg, not a zygote. If the egg is fertilized by a sperm, it becomes a zygote.
