Am I only 1% likely to be my Dad's kid?

[wordassociationfootball]

Last night I mentioned affectionately to my sis that I was imagining both our (deceased) parents smiling at us, their blue eyes twinkling. Sis (my only sibling) said Dad had green eyes. I just checked photos and his eyes were definitely blue. I had an odd feeling come over me so Googled whether two blue-eyed parents could have a green eyed (me) kid. 1% possibility. Can anyone gentically savvy increase the odds or tell me what they'd do in my shoes?
Full disclosure: When my Dad died I discovered he'd told my sis he wasn't my dad. I shrugged it off at the time as I'm like him/look like him in some ways... I always thought so anyway. There's a ten year gap between big sis and me. Mum had several miscarriages and they were on the brink of adopting when a pregnancy (me) stuck. I know that my mum had been in love with the husband of a couple they knew.
.... Holy mack mack, I cant believe how in denial I've been for so long about this. Thoughts please!

only sibling) said Dad had green eyes. I just checked photos and his eyes were definitely blue.

So your sister was wrong about that then?

I have very dark brown eyes and my parents had green and blue eyes - my son is the spit of my dad

My daughter has hazel eyes, her dad and I have blue eyes, she's deffo his!

I have green eyes and both my parents have blue eyes. I’m defo my dad’s daughter- we look a lot alike!

Neither therapist nor writer! If anything, a long career in IT has me approaching problems in a particular way - it's like my brain starts drawing a flowchart of possibilities as I read an OP and throwing up questions to me.

Why do you think your dad said this to your sister? What would he have expected her to do with the information? He'd kept his fear of not being your bio-dad from you for 30 years, after all - the man could keep a secret! Yet he told her. Was it out of the blue, or were they talking about something that sparked his disclosure - maybe medical, like hereditary disease?

both you and sis do a 23 and me kit. It’ll tell you if you are full siblings. Eye colour isn’t going to tell you anything definitive.

Have you been looking at US websites?

It used to be thought that you could only have blue eyes if your parents had blue eyes but it is far more complicated.

There are several genetic factors.

If it helps my dad has green eyes, my mum had blue, both me and my brother have blue eyes. I'm definitely my dad's child, we look so alike.

Green is technically a type of blue.

Oh and my dad's eyes 'change colour' depending on what he is wearing, sometimes they look deep blue.

I have brown eyes, my ex has brown eyes but our daughter was born with blue eyes which turned green as she got older. Grandmother on paternal side has blue eyes, and Great grand father on my side has Green eyes. So it's clear that myself and ex each are carriers of a recessive blue and green eye gene from our parent/grandfather which when passed down to our child has come together resulting in the eye colour she has.

@wordassociationfootball is it not your mum who has been the philanderer her though?????

Same !!

Yes, this!!

me: blue eyes. Both parents and all grandparents blue
dh: blue eyes. mil brown, pil hazel, at least one grandparent with striking blue eyes. No suspicion of infidelity anywhere.
DS: as green as can be. I presume some of DH’s side of the family’s brown/hazel came through.

the eye colour is not your smoking gun.

It’s good to see other blue eyed parents with brown eyed children on here! It’s very annoying that they still teach this as an impossibility in biology lessons!

@wordassociationfootball my brother and I tested last year as I found my paternal family after 46 years. This is the company we used

www.cellmark.co.uk

The results were just between me and him, completely private and came back within less than a week.

AncestryDNA is great but not if you don't want to see a bunch of other matches (possible other siblings maybe)

If you discover that you're half siblings and want to confirm who your paternal biological family are, then AncestryDNA would be your next option.

Hope this helps.

As far as I'm aware the two blue eyed parents is related to brown eyes specifically. There is still a chance even with that.

I'd be more concerned about what your dad said. Is you mum still alive? Do you want to know?

A test between you and your sister is not going to unearth a pile of random people, unless you go looking for them by posting your DNA results on some genealogy website.

Maybe you were IVF with donor sperm and/or egg. Your conception needn't have been sordid regardless of who your biological father is.

I have green eyes. Both my parents had blue eyes. I definitely belong to the both of them. Statistically it's a 0.2-0.3% chance.

This.

Even if all 4 grandparents had green eyes, there would still only be a 0.2-0.3% chance of having green eyes.

Those two phrases mean exactly the same thing.

Agree with PP that what your sister said is the bigger thing.

I wouldn’t rush into anything. Spend some time working out whether you want to know and how you’ll feel with the two possible answers. I know we all love a bargain but I think rushing into a test because of a special offer would be a mistake. I might start by talking it all through with your sister and trying to understand more about the exchange she had with your dad. When she told you you were in the first stage of grief which is a hard time to take things in.

Good luck whatever you decide.

No they don't?

My parents both have blue eyes and mine are green.

I hope they're actually my parents!

Even if you both did the Ancestry test there's no necessity to look at any other matches. You have a user name that doesn't need to identify you in any way, so In the event other matches wanted to contact you they would not know who you are and could only message you at Ancestry, which you can just ignore.

Same here, and they are definitely my parents. My sister also has blue eyes.
