DP seems to get annoyed when I disagree with him

[iwasagirlinavillage]

We had a conversation about DNA, inspired by the Madeleine McCann documentary, where I said that if a couple had enough children, does he think that two of them would have the same? It was purely speculative, and I understand that this is highly unlikely. It wasn't so much what the conversation was about, but more about the fact that he seemed to hate the fact that I have a different opinion to him. And his response was to seemingly get irritated with me as though I was being completely stupid. I was talking in the region of 50+ children, would that result in the same DNA between two siblings. As I say, I'm happy to be proven wrong on the point, I'm interested statistically but beyond that it was just a hypothetical conversation, but he seemed really annoyed that I couldn't grasp his point of view. It's caused a weird atmosphere between us. He couldn't seem to handle that my view wasn't the same as his.

Have you been drinking?

Bizarre thing to argue about!

Oh, ffs. Two people cannot have identical DNA. Try searching on Google. And how could a woman have 50 kids?! 🤔🤷‍♀️

He's probably horrified that anyone could be so naive

Even twins don't have the same DNA but if you didn't know that then you didn't know that. Sometimes I get frustrated with DH when he doesn't get something that I think is pretty basic so maybe it's just that surprise and frustration rather than being angry with you?

Well, is not nice that he got annoyed at you. I suppose it depends whether he was trying to explain that it couldn't really happen and then you were arguing with him. A quick Google would tell you "Theoretically, same-sex siblings could be created with the same selection of chromosomes, but the odds of this happening would be one in 246 or about 70 trillion. In fact, it’s even less likely than that".
So, it depends how the conversation went, whether he was just getting annoyed that you didn't understand what he was saying.

It's a bit of a stoner question, like wondering if you've ever seen the same pigeon twice.

Have you seen The Sopranos episode with Livia's funeral? I'm sure they have the same discussion about fingerprints.

No two people have the same DNA. Close enough to be sure of a relationship ( eg. parent, child) but the same? No. Not even identical twins.

You were being completely stupid. Hth!

Oh, OP. You silly sausage

There’s a difference between having a different point of view on something that is a matter of opinion, like Brexit (😱) and being wrong about something factual. It is exasperating to be in discussion with someone who is factually wrong but thinks their ‘opinion’ is equally valid.

As an avid true crime follower, I know that the
DNA regarding identical twins isn't that conclusive and there have been difficulties identifying which twin committed a crime.... and neither was convicted because they couldn't conclusively say which twin it was.

Do identical twins have the exact same DNA structure??

Identical twins share the exact same DNA at the time of conception. However, changes can occur after conception which can make their DNA differ. Likewise, even though their DNA starts out the same, exposures to the "environment" (harsh chemicals, for example) can change their risks for diseases to occur. So in the end, even identical twins can have minor differences in their DNA

Oh dear. Yes identical twins do have the same DNA.

This reminds me of the time my DH and I argued for over two hours (on and off not a marathon, but getting more heated as time passed) about whether the lighter I asked him to hand me was yellow - or orange... seriously until it ended in a weird atmosphere for about at hour until the final verbal bust up - which ended in hysterics when we realised what the f*ck we were actually arguing about.

We were a fair bit younger then and still smoked (I quit when I fell pregnant with my twins, he’s taken a bit longer but has cut down a lot and never near the DD and DS).

If this is consistent behaviour then I’d say it’s an issue, if this is a one off then maybe consider that it’s just one of those weird arguments?

"but more about the fact that he seemed to hate the fact that I have a different opinion to him."

You can't have a different opinion about a fact. You can only be wrong.

"but he seemed really annoyed that I couldn't grasp his point of view."

It wasn't his 'point of view', it was a clear scientific fact. Why couldn't you grasp it, out of interest? It doesn't seem that hard to understand.

He’s probably not annoyed at you for having a different opinion but I’m not knowing a very simple fact, and for presenting ignorance of that fact as a mere difference in opinion that requires the same level of consideration.

But hey if you didn’t know, you didn’t know. There’s a great course on Coursera on evolution and DNA, why don’t you take it and redeem his respect!

As PP said, it can only be a difference of opinion if it's an opinion. This is scientific fact.

Jesus I would get annoyed.

You are wrong. Factually wrong. And then keep saying well it's my opinion

It's like someone keep saying 'well its my opinion that 2 + 2 = 5. I entitled to my opinion and that's that's

It is infuriating.

Perhaps his irritation was due to a dawning realisation on his part that you are not well matched intellectually!

I blinked at the ‘odds of 1 in 246’, DogHair, and then realised that it was probably because your superscript had fallen off - should be 2^46, which makes sense.

You can't have a difference of opinion about a scientific fact. You were wrong OP.

I have a PhD in biochemistry and the simple answer for the purposes of a drunken argument is 'yes, if a couple have identical twins they will have two children with identical DNA'. Ignoring telomere aging.

Well said, @Count.

I would like to say that the people on this thread who laid into the OP must have inferiority complexes of their own,to be so enthusiastic about putting the OP down.

It is actually irrelevant whether the OP is right or wrong or thick as a plank. Her DH is in the wrong for being impatient and unpleasant about it. There is plenty that he doesn't know, including good manners. Seems it's not an unusual failing.

Did you accept that he has 'his point of view too? I have a friend who likes to play 'devil's advocate' and always wants a debate. It's so wearing when you just want to relax!
