To evaluate basic, general homophily within pairs of buddies, we calculated the kinship coefficient (21)

To evaluate basic, overall homophily within pairs of friends, we calculated the kinship coefficient (21) (the likelihood that two alleles sampled at random from two folks are identical by state), a measure that is corresponding to half the relatedness measure found in genome-wide complex trait analysis (GCTA) draws near (22) (even though the pairs of buddies listed below are maybe perhaps perhaps not really associated). Good values because of this measure suggest that genotypes are favorably correlated, and negative values suggest that two people are maybe maybe perhaps not associated and, in reality, are apt to have genotypes that are opposite. To determine heterophily, we calculated the empirical likelihood that two folks have other genotypes at a provided SNP, calculated because of the percentage of SNPs which is why neither allele is identical by state.

For comparison, we additionally calculated these measures for all nonkin “stranger” pairs with the exact exact same group of 1,932 topics who will be when you look at the buddies test.

For contrast, we additionally calculated these measures for all“stranger that is nonkin pairs utilizing the exact exact same collection of 1,932 topics that are into the buddies test. متابعة قراءة “The Friendship and normal selection in internet and system 1”
