Influence of genes in friendship
Genes affecting immune system did not appear to influence selection (possibly seeking different immune genes in incorporate into future offspring)
Linoleic acid may affect friendships (used as a pheromone in moths).
Olfactory senses appear to play a role in frienships
Friends have fewer opposing SNP's (p=4x10^-9)
Friendships comparative to fourth cousins (p-2x10^-16)
Heterophily- empirical probability of opposing genotypes among SNP's compared to proportion of SNP's without either allele similarity.
Homophily- Kinshp coefficient was calculated
Avoid ancestral errors
Stranger pair restricted to kinship less than or equal to 0
Only 907 pairs were used with kinship below or equal to 0.
Data from Framing Hearts Study analyzed for SNP's in 1,932 subjects.
People may actively seek out different phenotype friendships.
Environments may foster friendships among different genotypes
Third party may influence friendships
Environment can play a role
Friendship retention may be influence by genotype
Correlation may be influenced by geography and ancestry
