Is it likely his son is not really his?

Anonymous

This is more of a science question than anything. My boyfriend has three children. Two are in their 20s & one is late teens - one he already knows is not his because his now ex-wife cheated on him. The youngest one he knows is definitely his because she looks just like him. It’s like him with a long wig on. But he has a son that I was sort of wondering might not be his. He had never questioned it in front of me, and I never voiced my suspicions, but the other night he was drunk and finally said that he questioned sometimes the paternity of his son. My boyfriend is brown-eyed with brown hair. His ex-wife has brown eyes and is naturally a brunette. I know that both of my boyfriend’s parents are natural brunettes and I’m pretty sure they both have brown eyes also. His ex-wife’s mother has brown eyes and is a natural brunette. The only person I’m not sure about is his ex-wife’s father. I have no idea what his natural hair color is because he’s gray now, and I’ve never paid attention to his eyecolor. I don’t think his son looks like him at all. If he favors either parent, I would say he favors the wife more. He has some traits that are like his father, but those are personality traits that he probably woukd’ve gotten just from being around his dad, not necessarily a biological thing. I definitely don’t want to approach the subject with him anymore Unless he brings it up. I’m just curious. I feel so bad for him if it’s not actually his son because he dropped out of high school to start working so he could take care of his upcoming baby & future wife. Then she abandoned him and the kids multiple times for over a decade or more.
