Re: Gujars
You have just proven your ignorance on racial/genetic studies!
In the genetic studies, “South Asian” is used as a term representing distinct genetic traits/markers specifically dominant in the South Asian region. But like I said before no race is pure ! These South Asian genes are found all over the Middle East and Central Asia as a small minority. And obviously they dominate in India as the overwhelming majority (80-100%) except for parts of northwest India (E. Punjab, Gujarat, etc) where its more like around 60-70%. On the other hand in Pakistan, these genes only represent less than 50% of Pakistanis. The complete study can be found at: http://www.oxfordancestors.com/papers/mtDNA04%20DNALandscape.pdf
You are in denial of the fact that many Punjabis and Pashtuns look alike. In the above genetic studies itself, the genetic makeup for both ethnic groups is very similar. Skin color is irrelevant in racial/genetic studies which is more dependent on natural environment/climate and its long-term exposure.
In a 2004 Stanford study conducted with a wide sampling from India, including 112 Punjabis, and selected other countries, displayed the following: Broadly, the average proportion of mtDNAs from West Eurasia among Indian caste populations is 17%. In the western States of India and in Pakistan their share is greater, reaching over 30% in Kashmir and Gujarat, nearly 40% in Indian Punjab, and peaking, expectedly, at approximately 50% in Pakistan. It just proves that Pakistanis (including Punjabis) are by large racially/genetically distinct from Indians!
