Is it possible for a child to be more admixed than his parents?

[8888]

Let's put things this way: A couple is composed of two persons who are 85%-90% European and the rest East Asian, Native American, Australoid or SSA (only one of these options, could be any of them actually).
If they have a child it means the kid will be less Euro and more the other part than them? Like if his non-Euro ancestry would double down.

I think this could explain a phenomenon I see frequently of partial non-White people who look White having mixed looking kids.

What I mean is: will the kid be 30% East Asian/Amerindian/Australoid/SSA if both parents have around 15% or he will be around 15% too?

Its possible, because we have 4 grandparents and you dont receive equally from all, you receive 50/50 from parents but if all grandparents and all great grandparents are mixed, its possible that you are more mixed non-european then your parents.

Yeah. But let's consider both parents are 85-90% European. Will the child score less European than his parents or just look less European?
One mixed grandparent in each side, and one fully white. So the kid have two fully white grandparents and two mixed ones.

Both the father and the mother are in the 85-90% range. Will he actually be 70-75%?

not sure but i guess its unlikely he will that much non-european or that much more non-european, but lets say both are 90% bot have a non-white grandparent or mixed, he could receive more non-white from both parents, and be like 2-5% more non-white like they are 90 and he is 85 that cold be realistic outcome, but likely he will be close to both parents. thats the most usually case, that he again will be 90, but as for apperance even fully europeans vary in skin hair and eye colour and features etc. it could be that gives a more exotic vibe despite being equally european, as two 100 europeans can also differ it can also be that a 75 european looks lighter and less exotic then a 100 european also depends on if its nordic or med admixture etc.

Or being more direct, can European looking parents with both being 85% European and 15% Japanese have a Hapa or Japanese looking son?

unlikely but possible. there are throwbacks even. but its one in million. https://www.theguardian.com/theguardian/2003/mar/17/features11.g2

Interesting. You're right, I guess it's impossible for the kid to be significantly less European than his parents, something like 10% or 15% isn't really credible.
Because doesn't make sense two 90% European persons having a 75% child.

I guess with Japanese is probably different than with Black, like in the example you showed. Japanese would likely don't show phenotypically.

[Leto]

Genetically - I don't think so. Phenotypically - perhaps. Multigenerational mixes with admixture on both the paternal and maternal lines can turn out unexpectedly 'exotic' sometimes.

[Graham]

Yes.
