We all know that a baby is created from an egg of a mother and a sperm of father, and one egg ovulate each period month. But sometimes, there two eggs ripen same times. A woman's egg has a life span of 12 to 48 hours and a sperm can live for seven to 10 days in a woman's body. Maybe the mother has a sexual relationship with two different men within the same ovulation period that two eggs get fertilized by two different fathers. This is a very rare occurrence in humans. And scientists call this “Bi paternal”. One study estimated that it might occur in as many as one in 400 about 0.25% of twin births in America.
