Write two differences between ZIFT and GIFT

Answer»

Ans :- GIFT (gameteintrafallopian transfer) and ZIFT (zygoteintrafallopian transfer) are modified versions of in vitro fertilization (IVF).

ZIFT transfers a fertilized egg directly into the fallopian tubes whileGIFTutilizes a mixture of sperm and eggs.

In GIFT, the sperm and eggs are mixed together and immediately inserted.On the other hand, with ZIFT, the fertilized eggs --”zygotes”-- are inserted within 24 hours of the mixing.
