How Genes Shape Traits and Populations
Description
Genes shape traits and populations through inheritance, variation, and evolution. An organism’s phenotype, or physical traits, comes from its genotype, which is the set of alleles, or gene variants, inherited from its parents. Genes can also interact with one another and with environmental factors to produce traits in differ...

Transcript
Our traits depend on the genetic variants that we inherit from our parents. To understand why a person has a certain set of traits or “phenotype,” researchers study the function of individual genes and their alleles, and how genes interact with each other and the environment.
In this video, we’ll cover a brief his...
