Question

Trace the journey of the zygote until its implantation inside the uterus.

Answer 1

1. Fertilisation: Occurs in the ampulla of the fallopian tube.
2. Cleavage: The zygote undergoes mitotic divisions, forming a morula.
3. Blastocyst Formation: The morula transforms into a blastocyst.
4. Transport to the Uterus: The blastocyst moves through the fallopian tube into the uterus.
5. Implantation: Around day 6-7 following fertilization, the blastocyst embeds in the uterine endometrial lining, resulting in pregnancy.
