Quote by Robert M. Sapolsky

“If genes strongly influence average levels of a trait, that trait is strongly inherited. If genes strongly influence the extent of variability around that…

All the work on heritability was never based on looking at genes; it was based on the similarity between identical twins or between parents…

— Jerome Kagan

“These are crucially different. For example, how much do genes have to do with people’s scores averaging 100 on this thing called an IQ…

“As you study the trait in more environments, the heritability score will decrease. This is recognized by Bouchard: “These conclusions [derived from a behavior…

“Genes have plenty to do with behavior. Even more appropriately, all behavioral traits are affected to some degree by genetic variability.65 They have to…

Contrary to what we've been taught, genes do not determine physical and character traits on their own. Rather, they interact with the environment in…

“In the world of the extended phenotype, ask not how an animal's behaviour benefits its genes; ask instead whose genes it is benefiting.”

— Richard Dawkins

“Study a gene in only one environment and, by definition, you’ve eliminated the ability to see if it works differently in other environments (in…

Heritability pertains to the entirety of the genome, not to a single gene.

— Steven Pinker

The question is not whether but how do the actions of a given gene influence some interesting aspect of behavior.

— Jeffrey C. Hall

The interaction of the variation in our genes is what's responsible for lots of our attributes and vigor.

— Walter Gilbert

When a trait is universal, evolutionary biologists look for a genetic explanation and wonder how that gene or genes might enhance survival or reproductive…
