Some people say "races are socially constructed but ethnicities are not" but...

[Dušan]

Do you also think that races and sub-races are biological but ethnicities are socially constructed?

Ethnicities are mostly biological, too.
People used to marriage within the same ethnic group for centuries. Off course members of that ethnic group after tens of generations, share same genetic heritage.

Some ethnicities are not biological categories, but cultural, political, linguistic and religious. Like Italians and Turks for example. There is a huge genetic difference between Italians from Tyrol or Veneto and Sicilians, or between Balkan Turks and Turks from eastern Turkey or Cypriot Turks.
In Italy exist even huge linguistic difference by regions. From linguistic point of view Neapolitan and Sicilian are more separate Romance languages than just dialects of Italian language.

Yes, I don't deny the fact that people of the same ethnicity tend to be genetically close to each other but there might be some outliers and exceptions.

he rejected all japanese cultural aspects.
He didn't speak japanese and didn't like japanese food nor was interested to go to Japan... etc., etc.
Probably is an atypical case.. IDK...

I think he is an atypical one, Japanese usually like to
keep their traditions and Religion. Their Okinawan people outside Japan often join in their own communities. The same about Koreans and Chinese. My ex-uncle was Japanese descent (first generation outside Japan) and he has deep Japanese roots. I think they don't like Western traditions so much.

Really?

[reboun]

I still think ethnic identities are socially constructed and I have another point which is consistent with my statement: Pontic Greeks. They genetically cluster with Anatolian Turks, Georgians and Armenians but their ethnic identity is still Greek and are of the same ethnicity with mainland Greeks despite their clusters are a bit separate from each other.

Ethnicities' being socially constructed also doesn't mean that they do not have genetic basis. I do not ignore ethnicities' genetics basis and I think DNA tests might be useful to estimate ancestry and ethnicity. However, identification and culture are more important than DNA in terms of ethnicity, in my humble opinion.

Ethnicities are aligned to a core genetic structure.

True for Greeks, Germans, Poles, French etc

It seems you are complexed for not being true ethnic Turk, but Bosnian Muslim immigrant to Turkey.

If you are so concerned, you should find ethnic Turkish woman, as same should do your offsprngs for a couple of decades, and then you get grandchildren who will be by autosomal genetics 75% Turks and only 25% Bosniaks.
Simple as that.

...we don't know its connection with genetics.

did you just claim scientists do not know
which genes cause hair/skin/eye colour
or bone length, joint radius, et cætera?

Also, the phenotype is not equivalent to the genotype.
A Nordic Norwegian is genetically closer to an Alpine Norwegian than a Nordic Northern Italian.

this declamation is often seen on the inter-web, but,

it is never accompanied by actual examples to illustrate the claim.

will this be the first time?
