Polar body twins develop when an unfertilized ovum splits into unequal parts, and each part fertilizes by two different sperms. Usually, at the end of ovulation, the developing egg splits into two unequal cells with the same number of chromosomes. The bigger cell is called egg while the smaller cell is called the polar body. In most cases, the polar body degenerates and dies. However, in rare cases, the polar body is also fertilized by a sperm the same time when the egg is fertilized by another sperm. It, therefore, results in twins who share 75% of their genes (from the mother) and differ in the remaining 25% (due to two different sperms from the father) (4).
