Question

Differentiate between the Following:

Fertilisation and Implantation

Answer 1

Sr. No.	Fertilisation	Implantation
1.	Fertilisation is the fusion of a sperm and an ovum to form a zygote.	Implantation is the attachment of the blastocyst to the inner wall of the uterus.
2.	It usually occurs at the ampullary-isthmic junction of the fallopian tube.	It occurs in the uterus, about 6–7 days after fertilisation.
3.	It begins the development of a new individual by forming a zygote.	It allows the developing embryo to become established in the uterine lining.
4.	It involves the union of the male and female gametes.	It involves the attachment of a developing blastocyst, not the fusion of gametes.
