I have an idea, but I'm comfused. I heard that its when a sperm fertilizes an egg while another fertilizes a polar body. But aren't polar bodies supposed to deteriorate? Confused!

I have heard of this and if I remember correctly its when spem from 2 different donors implant an egg and then the egg splits as it would normally for identical twins. The only way this would be possible would be during a threesome.

An egg can split prior to fertilization, and be fertilized by two different sperm, this would be your 'half twin' scenario. Technically, a polar body is an infertile egg, but weird things can happen in the human body.

Twin:
One of two children produced in the same pregnancy and born during the same birth process.
Twins can develop from one ovum (egg) or from two ova (eggs):
Twins from one ovum: Twins that develop from a single ovum are called monozygotic. They are said to identical twins and have identical genomes.
Twins from two ova: Twins that develop from two ova that are fertilized at the same time are called dizygotic. They are nonidentical twins and have different genomes.
The term "fraternal" is often applied to nonidentical twins but it may be misleading. Nonidentical twins can be of the same sex (two brothers or two sisters) or of different sex (brother and sister). The better term is "nonidentical."

half identical twins are also called fraternal twins that is when two ovums get frtilized by two sperms so they are not identical twins but half identical twins
