DNA test

Why would it be different? By doing this test you set the tone that he can make unreasonable demands on you and you will jump through the hoops because you love him.

In your shoes I would have the test and reconsider the relationship.

I would be livid if my partner was asking for a DNA test
We have 5 children and they are all different
i have dark brown hair and dark brown eyes
Dp has Brown hair and green eyes
Ds1 Red curly hair and blue eyes
Ds2 Brown straight hair and light brown eyes
Ds3 Red straight hair and dark brown eyes also looks nothing like Dp
Ds4 Brown curly hair and blue eyes
DD Red curly hair and green eyes
All very different but have the same parents
Genetics is a funny thing

Less than one percent still means there is a chance according to your theory of eye inheritance.

Btw eye colour and hair colour in humans doesn't follow mendelian inheritance.

Your partner is not at all reasonable. Asking for a DNA test is totally ridiculous, and really disrespectful.

Interesting because I have green eyes as did one of my parents. Other had brown. Dh blue eyes. 5 kids 4 blue eyes 1 brown eyes. All have similar facial features though and all share lots of features with extended family.

I have 3 kids and they are blonde with different coloured eyes (blue, green and brown). Their parents are both brown hair so it must be the grandparents’ genes that resulted in their hair colour. Genes do weird things sometimes.

Let's get an actual geneticist in on the "blue eyed parents can't produce brown eyed child" myth: https://udel.edu/~mcdonald/mytheyecolor.html

I would be furious because he’s saying that you cheated.I would do the DNA test and break up with him because there’s no coming back from an accusation like that. I bet you’ve spent years reassuring and possibly being accused but it’s clearly been pointless if he thinks that you’re a cheater. If he’s insecure then he shouldn’t be in a long-term relationship because it’s unfair on his partner.

They are recessive too

One or two brown eyed parents might have a green or blue eyed child

two green or blue eyed parents cannot have a brown eyed child

Where does green eyes fit in

There is in fact a less than 1% chance that two blue eyed parents can have a brown eyed child.

I would consider it almost certain if two blue eyed people ended up with a brown eyed child that the woman had had an affair, and I wouldn’t blame any man for questioning whether the child was his.

Yes if you’re saying you and the father of the child both have blue eyes and the child has brown eyes it’s impossible.

But two blue eyed parents can’t have a brown eyed child because blue is recessive and brown dominant.

I would be fucking livid if my dh suggested that one of our dc might not be his, but he wouldn't, it would never even occur to him.

I don't but then I have some of the recessive genes from my parents, my DD displays them as well, and I know plenty of others who show them.

Me and husband also have a blonde and blue eyed boy where as our daughter is quite dark, i did a My heritage ethnicity DNA test for our whole family, Yes the kids were proven to be both his although he never doubted but was also interesting to see where the blonde could have come from and

Indeed. I did DNA via ancestry and it came back with 42% Scandinavian (and a host of others, including 1% Nigerian, 2% East Asian). My heritage is very firmly in Yorkshire, so it made complete sense.

It'd be a deal breaker for me, too. How you could continue to have a normal marriage with a man who's prepared to toss accusations like that around and then pretend nothing happened I can't imagine. Accusations of cheating are profound questions about the foundation of the relationship.

I have mixed views on this.

My initial thought was that I would immediately end the relationship, and would do the DNA test with child maintenance in mind.

But if a child bears absolutely no resemblance to someone it’s not unreasonable to wonder. The number of children who aren’t biologically their fathers’ is high. Between 5-10%. And actually, while people are taking this seriously because we’re talking about a child, these same people would have no qualms in advising an OP to check someone’s phone/have them followed if they believed them to be cheating.

I think it can be hard to think of this from a man’s perspective, because it’s something which can’t happen to a woman.

But as much as people say that it’s naive to think a man would never cheat, it’s also naive to think that a woman wouldn’t have an affair and end up with a child as the product of that affair.

There are clearly trust issues in the relationship, and in truth a child which has no resemblance to their parent is no less of a red flag than a man who spends too much time on his phone.

I honestly think that would be a dealbreaker for me.

He’s just accused you of being a liar and a cheat. I couldn’t get past that.

Men in my family try this nonsense with the expression of recessive genes, they however aren't stupid enough to say their baby or toddler isn't theirs.

At some point one of the child's other blood relations will point out they the same recessive trait that the child had or has though the child maybe a teen by then.

I would do the test but personally I would hand him the results with a note saying “f you for doubting me, I am out of here” .

I am not, I am assuming the DNA test will prove that. I am just saying I understand why the partner wants reassurance
