Two sets of twins to a mixed couple. In both cases, one twin is white and the other black.

I've heard about ^this^ happening multiple times. There was a couple in Africa who were both of pure African descent(or so they thought), but they had a white child together, because somewhere along the line they both had just a bit of white mixed in. There was also a mixed race couple, both were half white half black, in America, who had twins, one full black the other full white. Genetics isn't an even thing, I look much more like my mom than my dad, but that by no means proves that mother cheated on him (which is an absurd thought).

Awesome ReenaC!!!! "liking" your post!!!

I know a lady, who is white and her husband is white but their youngest was born black. After 3 white kids, their 4th together was black.

It is possible and Jacob is the most hilarious little guy ever.

I would do the paternity test just so that Cadence will have her grandparents in her life as she grows. It is unfair of her grandparents to alienate her in such a way just because she has a light skin tone. I have a mixed niece and I know from experience that not all mixed babies are born with dark skin. Most likely her skin will darken as she gets older my niece practically lives in the sun during the summer and often gets so dark you wouldnt think her mother is white, lol!!! I hope that everything works out for you and your family.

Oh. My. Word. I can't believe she would act like that. Especially since her side of the family has a mixed heritage, you would think she would be much more open-minded. How interesting and hypocritical. I would do like, everything everyone mentioned so far. First of all, state your case clearly, again, and emphasize how offended and hurt you are, and even more emphasize your love and devotion to Kyle and y'all's children. Discuss how even Kai's complexion has changed--and she didn't say anything about that. I would even show her the cases where a couple who were both mixed themselves (the mom and the dad had like an in-between skin tone/light to medium brown) and they had twin girls--one who was very dark brown/much darker than both parents, and one who was so white with blond hair. I'll try to find it for you--it's really cool. I would hope after discussing it seriously once more, she'll come around, apologize, see the error of her ways, and say she was just teasing. If not, and it gets worse, I would say then that maybe you'll do the paternity test at her cost, and go from there. Best wishes.
