His early research examined centrarchid population genetics, gene expression, reproductive physiology, and strategies, heritability of fish behaviour, and life history strategies.
en.wikipedia.org Inheritance patterns in families, heritability and genetic correlations, molecular markers, and associations have been studied.
en.wikipedia.org These three main experimental types are used in animal studies, studies testing heritability and molecular genetics, and gene interaction/environment studies.
en.wikipedia.org To express the portion of the variance due to the nature component, behavioral geneticists generally refer to the heritability of a trait.
en.wikipedia.org Since heritability is less than 100% and symptoms vary markedly among identical twins with autism, environmental factors are most likely a significant cause as well.
