EXPLORING HOMOPHILY AND HETEROPHILY IN GENOTYPES
EVOLUTIONARY MODELS AND GENETIC CORRELATION
Inclusive fitness theory: This evolutionary framework suggests that individuals may exhibit altruistic behaviors towards genetically related individuals to increase the transmission of shared genes.
. Genetic correlations between individuals are shaped by kin selection and the benefits of cooperation among relatives.
Environmental factors cause HOMOPHILY in genotypes
Common experiences and cultural factors may reinforce homophily in genotype
Shared environments, such as neighborhoods, schools, or workplaces, can facilitate interactions between individuals with similar genetic backgrounds
GENETIC DIVERSITY CAUSES HETEROPHILY
Heterophily in genotypes arises from genetic variability within populations.
Genetic mutations, recombination events, and assortative mating contribute to the genetic differences observed between individuals.
EVOLUTIONARY MODELS AND GENETIC CORRELATION
Evolution of cooperation: Genetic correlations in social networks can be explained by evolutionary models that emphasize the fitness advantages of cooperative behaviors.
Mechanisms such as reciprocal altruism and indirect genetic benefits contribute to the maintenance of genetic correlations in populations.
GENETIC-WIDE ANALYSIS IN CORRELATION IN GENOTYPES BETWEEN FRIENDS
Genome-wide association studies (GWAS): These studies examine genetic correlations between friends to identify genomic regions associated with social interactions and homophily
GWAS analyzes millions of genetic variants across the genome to uncover associations with specific traits or behaviors.
GENETIC FACTORS CAUSE HOMOPHILY IN GENOTYPES
Individuals may exhibit homophily in genotypes due to shared genetic ancestry or familial relationships.
Genes that influence personality traits, interests, and behaviors can contribute to the formation of social bonds among genetically similar individuals.
Findings
Theses finding support the role of genetics in shaping social networks and friendship formation
Research using GWAS has revealed significant genetic similarity between friends, particularly in genes related to personality traits, behaviors, and social preferences.
ENVIRONMENTAL CAUSES YIELD GENETIC HETEROPHILY
Environmental variation plays a significant role in shaping genetic diversity among individuals.
Different environmental pressures, such as geographic location, socio-economic status, and cultural practices, can lead to heterophily in genotypes
Exploring Homophily and Heterophily in Genotypes
Future Directions
Future research may focus on elucidating the complex interplay between genetics, environment, and social dynamics in shaping genetic correlations.
Longitudinal studies, cross-species comparisons, and integrative approaches will advance our understanding of the genetic architecture of social networks.
Positive Selection
Homophilic SNPs are genetic variants that have undergone positive selection due to their association with social traits or behaviors.
Positive selection favors alleles that enhance social compatibility, cooperation, or mate choice, leading to genetic correlations between individuals.
Implications for Positive Selection
The identification of homophilic SNPs provides insights into the evolutionary mechanisms driving social behavior
These SNPs may confer fitness advantages in social contexts, influencing the formation and dynamics of social networks.
Implications
Understanding genetic correlations in social networks has implications for various fields, including evolutionary biology, psychology, and public health.
Insights into the genetic basis of social behavior can inform interventions aimed at promoting positive social interactions and well-being.
