a new kind of twin?

[Freshgeardude]

I was looking on cnn and in an article it says that there is a new, rare kind of twin called semi-identical. It basically is one egg 2 sperm and separation. both have all of the mother's genes but one of them has half of the father's genes. its pretty weird heres the link

According to a study published in the Mar. 28 issue of Human Genetics, two sperm fertilized one egg and created the twins. The phenomenon occurs in about 1% of the population, but most embryos created in this way ? called triploids because they have three sets of chromosomes ? do not live. Says Dr. Mary Jane Minkin, a clinical professor of obstetrics and gynecology at Yale University: "This confirms that two sperm can get into an egg." Normally the cell dies. But Minkin makes a valid point: "Never say never in medicine and biology."
