  1. Populations which have remained near their origin will show a lower proportion of long alleles of DRD4 than those that migrated further away (312).Chen, Chuansheng - Population migration and the variation of dopamine D4 receptor (DRD4) allele..., 1999 - 2 Variables

    Dopamine receptor D4 (DRD4) exhibits the largest number of polymorphisms of any dopamine receptor yet identified, and variation in DRD4 has been linked to variation in traits such as novelty-seeking and attention deficit/hyperactivity disorder. DRD4 also exhibits large variation between populations. Here, the authors test the hypothesis that natural selection acting on DRD4 may account for variation in between-population migratory patterns, using genetic and historical data from 39 populations.

  2. Within each region, societies with the lowest percentage of long DRD4 alleles will tend to be sedentary, while societies with the highest percentage of long DRD4 alleles will tend to be nomadic (313-314).Chen, Chuansheng - Population migration and the variation of dopamine D4 receptor (DRD4) allele..., 1999 - 2 Variables

  3. Population level variation in DRD4 alleles is attributable to general bottleneck effects that also acted on non-DRD4 genes (317).Chen, Chuansheng - Population migration and the variation of dopamine D4 receptor (DRD4) allele..., 1999 - 2 Variables

DRD4 also exhibits large variation between populations. Here, the authors test the hypothesis that natural selection acting on DRD4 may account for variation in between-population migratory patterns, using genetic and historical data from 39 populations.

  4. Population-level variation in DRD4 alleles is a result of the distributions of DRD4 alleles in founder groups (317).Chen, Chuansheng - Population migration and the variation of dopamine D4 receptor (DRD4) allele..., 1999 - 2 Variables
