Question

What is fertilizin and where is it produced?

Answer 1

Present in the gamete of the female which helps in the one major phase of reproduction without this chemical correct mating of gametes of the same species cannot occur. It occurs when the sperm is ready to fertilize the egg in the uterus of the female body.

Complete answer:
Fertilizin is present on the outermost layer of the ovum or the egg of the female gamete.
Fertilizin is made up of glycoproteins or say mucopolysaccharide and is present as a chemical sheet on the egg.
This is a kind of chemical produced when the egg becomes matured and ready for fertilization.
This fertilizin secretion can only be recognized by the antifertilizin.
Act as a guide for the sperm as on sperm, an antifertilizin is present (on the head of sperm ) which when comes in contact with the fertilizin chemical signal moves towards the egg and gets fused with it.
If the fertilizin and antifertilizin don't match with each other fusion components fertilization will not occur.
It gives an error-free way to fuse the egg of the same species, that’s why fertilization between two different species doesn’t occur.
The whole process occurs inside the uterus or the utro-fallopian tube of women.

Note: It is a very essential process of fertilization if fertilizin isn’t produced in the right amount, sperm will not get fused in the egg, both chemicals antifertilizin and fertilizin work together as a part to work the fertilization process correctly.
