Surveying Genetic Variation in Populations

An important topic in the field of population genetics is speciation, the process by which populations become distinct species. Studies like this one can help scientists determine if two or more populations have genetically diverged into separate species.

For example,deer phenotypes can be places into one of two categories: efficiency, which promotes survival over extravagant antler growth, and luxury, which promotes the growth of large, dangerous antlers. 

To determine the different effects of environment, nutrition, and genetics on antler phenotypes, researchers relocated wild individuals to controlled captive facilities to measure antler growth across first- and second-generation offspring.
