Blue Eyed Father, Brown Eyed Mother = Always Brown Eyed Child?

39 posts in this topic

If a blue eyed farang has a child with a brown eyed Thai women, will the child always have brown eyes or can the child also have blue eyes?

Brown is a dominant colour in eyes but blue eyes are possible. Please note eye colour ar birth can give a false colour for up to 2 years

This would only be remotely possible if the Thai had a recessive blue-eyed gene (there are two main genes controlling eye colour not just one).

Thais would never have this unless their ancestry included a person with a blue-eyed gene, eg a european, and even then the chances of a blue-eyed child would be extremely low.

So it's a probabilility of pretty much zero, and completely zero with no foreign ancestry in the Thai.

Only exception would be if the Thai female had a completely new mutation for blue eyes that arose in one of her eggs and that was the one fertilised. This does happen, but here it would a probability so low that you could exclude it. But you could test for it.

Explanation of principle is here, in not too confusing article: http://genetics.thetech.org/how-blue-eyed-parents-can-have-brown-eyed-children

The old blue eyes - there are only 11% of us in the population I'm told and even less if you are left handed, and we all came from a common ancestor somewhere in Turkey. Isn't it good to be different !

Not great to be left handed according to mortality rates. smile.png

It's a right handed world which makes it a dangerous place for you guys.

Partington already covered what i came to say.

Thai's with Blue eyes are just using contacts.

So basically no chance of fostering a new 'breed' of blue eyed half asian half farang children? Unless if you have a child with a half farang girl in the first place, then you may or may not stand a chance?

There is no chance unless your Thai partner has some foreign ancestry, but it needn't be a parent. A grandparent (or great-grandparent, or even further back) would still make it possible. Otherwise no...

Looks like that.

Blue = recessive

Brown = dominant

So, more likely chance for brown eyes, unless she has blue eyes somewhere in her genes.

Half Thai, brown eyed dad. Blue/Green eyed mother. We produced a very blue eyed girl.

Yes that's not unusual- half-Thai Dad can have a gene for blue eyes, and a gene for brown eyes - his eyes are brown because the brown-eyed gene is the one that shows up (= dominant).

There's only one of each gene per sperm: a blue-eyed gene sperm fertilized a blue/green-eyed gene egg = child with blue eyes.

Me blue eyes, mother dark brown eyes, 3 children light brown eyes.

Assuming my children all give me 2 x grandchildren each and marry a blue eyed person.

Then there is a strong possibility of 2 or more grandchildren having blue eyes.

At the end of the day, so long as their all healthy and happy i don't mind what colour their eyes are!
