Two close college friends discovered recently they were actually half-sisters from the same sperm donor.
Mikayla Stern-Ellis and Emily Nappi became fast friends at Tulane University after discovering they had a lot in common. Then, over winter break, the two college freshmen friends learned they were half sisters, according to the school newspaper, The Tulane Hullabaloo

"We thought [going to Tulane] she'd just find an education," Debra Stern-Ellis, Mikayla's mom, told the Hullabaloo, "but she found a sister."
Stern-Ellis, 19, and Nappi, 18, met on Facebook during the roommate search process. Though Nappi already had a roommate, they stayed in touch through the social networking site. Through these conversations, they discovered that they both were conceived with the help of a Colombian sperm donor and joked with each other about the possibility that they were related.
"We've been telling people, 'There's a 25 percent chance we're sisters,'" Nappi told the paper.
It turned out to be true when the girls learned they had the same donor number, leaving their families amazed.
"This is just one of the many amazing gifts she's gotten from going to Tulane already," Heidi Stern-Ellis, Mikayla's other mother, told the paper.
The half-sisters have since identified many commonalities that they attribute to their shared genes. Both are performers in Tulane's upcoming production of the "Vagina Monologues" and love acting.
"[On his profile] it says that [the donor] did drama as one of his interests," Debra Stern-Ellis added.
It turns out the teens also bought the same jacket on Black Friday without knowing the other had bought it too.
