Does the color of the skin determine the degree of genetic relationship?

The degree of genetic relationship is determined by how long ago the ancestors of the two groups in question interbred seamlessly or as a unit. I gather that there is not enough intermediate data in form of DNA to accurately determine the level of genetic relatedness of human groups.
The Yoruba as an example must have been reproductively isolated from any East or South African group for as long as they have been isolated from any Celtic, Germanic or Slavic group in Europe, the similarity or lack of it of the hue of the skin notwithstanding.
The average hue of the skin or the average pigmentation in the skin of an ethnic group is determined by the latitude of their habitat on Earth surface and it is nothing more than that. Australoids who look like west Africans are more genetically related to Europeans than they are to any African group. Human phenotype is adaptive to the habitat. Slavs in Russia for instance were definitely reproductively isolated from Celts before the modern era or before the industrial revolution for as long as they have been isolated from any African group but both groups are pigmented to approximately the same degree.
All nations are made up of immigrants and I have some Irish and Viking in my DNA make up apart from others. The only difference is that some nations like the USA, Brazil and etc were birthed recently. My family have been IJESA for less than ten generations, maybe for around three hundred years while IJESA is just less than 1500 years of age as a nation. Whether birthed recently or long ago, a nation is a nation. As a nation, you have your identity and you are genetically related to your neighbors and trade partners that you interbreed with while your identity is unique to you and branded by language, cultural practices and etc
A nation like the USA is made up of native American, European, West African and other ancestry. Modern Yoruba is made up of inputs from neighbors, European and other ancestry. All nations are like that.
Nations therefore are ethnic and etc in identity and the Earth is not divided into colors or continents but into nations of people and a fair skinned group might be more related to a dark skinned group than they are to any fair skinned group just like the dark skinned Australoids in Australia are more related to Europeans than to Africans.

I do not think any group can live in a particular habitat for more than a few thousands of years before the habitat is stamped on their average phenotype.

Interesting fact: skin color does not affect DNA testing! Regardless of skin tone, each of us has unique DNA and is of enormous scientific value. This is a reminder that our differences only enrich humanity and do not change the essence of our biological makeup.

That's a great point! Indeed, skin color does not affect DNA, and this highlights our common biological basis. Every gene in our DNA, is a clue to our origins and health. I found it interesting to read MyHeritage reviews and learn how DNA research helps people learn more about their heritage and family ties, regardless of outward traits. It proves once again that genetic data is universal and equal for everyone. Such research provides insight into how our unique genetic traits affect our health and ancestry, emphasizing that in a scientific context, we are all the same.

My whole point is that some light skinned people are more related to some non light skinned people than they are to other light skinned people and etc. Australian aborigines are more related to Europeans than they are to Africans despite being dark skinned. Yoruba might be more related to Germans than they are to East Africans and etc given the distance between them. We can not say genetic data is equal for everyone like you said. I hope you see my point
