Kin Selection and Genetic Similarity Theory.

J.P. Rushton's Genetic Similarity Theory is not widely appraised by the mainstream of the scientific establishment in North America, Europe & Australia. Rushton and a small handful of collaborators at the University of Western Ontario have tried to reinterpret the general theory of Kin Selection, which was originally invented by W. D. Hamilton, Colin Pittendrigh, and George C. Williams. Using Hamilton's rule, Rushton has tried to derive a generalized theory about human sexual attraction among genetically close kin. Accordingly, Rushton postulates that people will instinctively find those who resemble their own family to be more attractive than outsiders.

Is there any scientific evidence at all to suggest that intra-ethnic sexual attraction among genetically close kin is biologically determined to some degree; and if so, what is the heritability of the biological component responsible for intra-ethnic sexual attraction among genetically close kin?

On the other hand, how much of a role do environmental factors play in terms of one's acquired sexual taste (as a percentage of the individual's overall psychological development) as opposed to the individual's biologically determined intra-ethnic sexual attraction, which would be the basis of inter-ethnic sexual attraction between different kin groups?
