Probably not identical. One egg was fertilized by a white man, the other by a black man. Here is some info I found:
Indeed, medical research has shown that when a woman has sex with two men within the same ovulation window, it can result in bi-paternal twins, known as heteropaternal superfecundation.
Hilda Hutcherson, a clinical professor for obstetrics and gynecology at Columbia University, said fraternal twins come when a women releases two eggs during ovulation instead of one — and both eggs are then fertilized.
With bi-paternal twins, she said, each egg is fertilized by a different man's sperm.
Hutcherson said eggs can live up to 24 hours in a woman's reproductive system. Sperm, on the other hand, can live up to five days in the woman's body, she said.
So, Hutcherson said, it is possible that a woman could have sex with one man on Monday and have sex with a different man on Wednesday — and then when her eggs are released on Thursday, the two men's sperm living inside her could each fertilize an egg.
