Kaplan therefore concludes that, while differences in particular allele frequencies can be used to identify populations that loosely correspond to the racial categories common in Western social discourse, the differences are of no more biological significance than the differences found between any human populations (e.g., the Spanish and ...
A graphical representation of the typical human karyotype The human mitochondrial DNA. Human genetic variation is the genetic differences in and among populations.There may be multiple variants of any given gene in the human population (), a situation called polymorphism.
[1] The northern group of Russians are closest to the Finnic-speaking peoples. Russians display quite significant genetic heterogenity, evidence for multiple genetic ancestries and admixture events, and high identity-by-descent sharing with the Finnic people among the population of the north-east of the European part of Russia .
An ethnicity or ethnic group is a group of people who identify with each other on the basis of perceived shared attributes that distinguish them from other groups. Those attributes can include a people of a common language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment.
Another way to look at differences between populations is to measure genetic differences rather than physical differences between groups. The mid-20th-century anthropologist William C. Boyd defined race as: "A population which differs significantly from other populations in regard to the frequency of one or more of the genes it possesses.
A wide range of methods have been developed to assess the structure of human populations with the use of genetic data. Early studies of within and between-group genetic variation used physical phenotypes and blood groups, with modern genetic studies using genetic markers such as Alu sequences, short tandem repeat polymorphisms, and single nucleotide polymorphisms (SNPs), among others.

Small differences were found, but those were not based on race. They were from biological differences caused from the region in which the people live. They describe that the small differences cannot be fully explained because the understanding of migration, intermarriage, and ancestry is unreliable at the individual level.
On one end are people who would argue that Down syndrome is not a disability but a mere "difference," and on the other those who consider it such a calamity as to assume that such a child is better off "not born". For example, in India and China, being female is widely considered such a negatively valued human difference that female infanticide ...
