1. Humans and other animals have many phenotypic variations in eye color. 2. Thus, interfamilial phenotypic variation will be greater than intrafamilial variation. 3. It reduces phenotypic variation and maintains the status quo. 4. There are many different ways in which the phenotypic variation can play out. 5. There were 3 quantitative trait loci that explained most of the phenotypic variation . 6. This increase in phenotypic variation has the potential for transgressive segregation to occur. 7. Researchers have also uncovered a genotype by diet interaction that drives phenotypic variation . 8. Heritability is estimated by comparing individual phenotypic variation among related individuals in a population. 9. Weinberg pioneered in phenotypic variation that partitioned this variance into genetic and environmental components. 10. Haldane proposed that there exist three possible sources of observed phenotypic variation in monogenic traits:
