From MSNBC, and as discussed in class last week:
Mother gives birth to twins with different dads ‘One-in-a-million’ occurrence involves two eggs and two different fathers
A Texas woman wasn't planning on two conceptions for the record books.
But that's what she got — along with two beautiful boys — when she gave birth to twins of different fathers nearly a year ago.
"Both of them have similar appetites. They like to play with their older brothers. They like to play with each other," Mia Washington told the TODAY show Thursday.
Talk about baby-papa drama.
How did it happen? Every month a woman's ovary releases one egg that can be fertilized by one sperm. But in this case, a pair of eggs emerged.
Sperm, meanwhile, can remain alive and well and viable for up to five days in the reproductive tract. Thus a woman can have sex with different men within those five days and the sperm “just kind of hang out there waiting for the egg to be released,” Dr. Hilda Hutcherson, Clinical Professor of Obstetrics and Gynecology at Columbia University, told Meredith Vieira on TODAY.
Washington, who just turned 20, admitted to her partner that she had sex with another man within that five-day window — hence, the double conception.
The mystery began to be solved when her partner, 44-year-old James Harrison, became concerned that Justin and Jordan, born only 7 minutes apart, looked so different. A paternity test followed.
When he discovered that Justin wasn’t his son, Harrison said, "I was hurt, torn apart — didn't know what the next move was gonna be," Harrison said in a taped NBC News segment.
Nonetheless, he's loved both boys the same since then. "I raised him [Justin] from a baby all the way to now. He knows me as his father, and I know him as my son," Harrison explained.
