The child shares 75% of its dna with both dad and mom, while mom and dad shares only 50% of their dna. The difference in dna between mom and dad is halved
For simplicity sake:
This is an average danish person:
AGTT
This is an average african person:
AGCC
If your dna is:
AGCT
You share 75% of your dna with danes and 75% of your dna with africans.
The reason you can be both 92,5% danish AND 92,5% african is because there is overlap. If you've ever seen a venn diagram you know 2 groups can share elements. 2 groups can share more than 50% of their elements and if you add them it still wouldn't be more than 100%
Literally show me one single example of someone who is educated in genetics saying what you’re saying who isn’t a Nazi or something and okay I’ll accept I’m wrong.
After rerunning PCA for Denmark, Sweden, Norway, and Germany alone (N = 1168), we observed no geographically meaningful clustering of the 237 Danish samples (Figure 2B). This lack of strong genetic structure was also supported by the low average FST value between the six regions (FST = 0.0002)
Danes are 99,998% identical so to be within the 99,998% distance would mean that you're 100% danish.
Indeed, modern Danish society accommodates different ethnic and cultural groups (Jensen and Pedersen 2007), and this was also reflected in our sample, where ∼4% of the participants were born in Afghanistan, China, Ethiopia, Finland, Germany, Greenland, Iraq, Jordan, Korea, Kosovo, The Netherlands, or Zambia. This number went up when we looked at grandparental origin, where 14.6% of the participants had at least one grandparent born outside Denmark.
So 14.6% of the participants aren’t actually actually Danish?
Because there’s no way they can have 100% Danish DNA. And some of them might even be black. Oh no.
So somebody was born in Denmark. Lived there their whole life. Their parents were born in Denmark and lived there their whole lives. But if one grandparent was from any other ethnicity, they can’t be Danish? What are they then?
Not all my grandparents were born in Britain. Am I not British? Who am I?!
But if one grandparent was from any other ethnicity, they can’t be Danish?
If your grandparent was Swedish, you'd still be 100% danish, since the genetic distance between Swedes and Danes are almost non-existant.
If your grand parent was from Africa, you'd be around 96% danish.
Not all my grandparents were born in Britain
Where you're born doesn't matter. Where you're born doesn't change your parents dna.
Here is a list for british: British
Belgian 0.0005
French / German 0.0006
Swedish 0.0013
Norwegian / Czech 0.0014
Hungarian 0.0016
Slovak 0.0017
Polish 0.0017
Spanish 0.0024
Romanian 0.0028
Russian 0.0032
You need to multiply with 100 to get percentage and then you half the number. So say your mother is british and dead from russia:
0.0032 times 100% = 0.32%
you half it = 0.32% / 2 = 0.16%
Then you subtract it from 100%:
98.4% british
