Son has straight hair when his dad has Afro type hair

[indigo277]

My partner is mixed race with Afro type beautiful curly hair. He has a daughter from a previous relationship- her mum is white and his daughter has curly Afro type hair like him.
We have a 16 month old son who has dead straight hair like mine with no sign of even a wave! How can this be?!

I guess that although afro hair is dominant, the likelihood of passing on the afro gene or the straight hair gene are equal. And if your x is mixed race he has both genes. One recessive, one dominant, but an equal likelihood of each being passed on.

He's just taken after you that's all x

Why couldn’t it be? He is a mix of both your genes.

He’s got a straight hair gene from his dad and a straight hair gene from you. His dad must have a recessive straight hair gene.

Is this a serious question? I’m mixed race and have straight hair like my mums who is white

Either his DDad has 1x afro and 1x straight hair genes and your DC has had straight hair genes from both of you (50/50 chance, assuming you have 2x straight hair genes)

Or he has an afro gene but for some reason it's not fully expressed

Basically like @JoyPeaceHealth says except that hair texture and skin colour are determined by many genes not just one. Your partner has genes for both straight and Afro hair (from each of his parents). He passed more of the Afro hair genes to his other child and more of the straight hair genes to your child. Two mixed race parents can have children much lighter or darker than either parent depending on which genes get passed on.

Well your DC is 1/4 Afro-Caribbean and 3/4 white (I'm assuming here, apologies if I'm wrong) so why not straight hair?

Oh I misread it and thought your partner was black now I'm even more convinced this isn't real, of course a child that's only 1/4 black will appear more white/ have more white features, jade goody 's father was mixed race

I've got one dc with brown hair and one dc with red hair from the same dad. They just inherit different things.

Afro hair is a texture not simplified to curly / straight and it isn’t more ‘dominant’ than European hair textures (most Indians have Afro hair that is straight for example and as we get older the texture coarsens).

Because that is how genetics work. A good friend of mine (mixed race) has a son with dark Afro hair, one who is v pale and freckled with blonde curly hair and one who has the most beautiful straight glossy blonde hair

How long is it? It’s not unusual for boys of mixed ethnicity to have quite straight looking hair but their sisters to have quite curly hair (although many girls use straighteners when older)
However if the boys ever grow their hair (e.g. during the pandemic) you will notice their hair is actually just as curly. It’s also quite common for the baby hair to be quite straight so if this was the only time the child had longer hair then it’s not a true reflection of their hair when older

Genetics? Not sure why it's so surprising. I'm mixed race but have fair features whilst my sister has darker features.

This is a strange question...

The way you've phrased this seems really odd.
