How to Calculate Narrow Sense Heritability

A central question in biology is whether observed variation in a particular trait is due to environmental or to biological factors, sometimes popularly expressed as the “nature versus nurture“ debate. Heritability is a concept that summarizes how much of the variation in a trait is due to variation in genetic factors. Often, this term is used in reference to the resemblance between parents and their offspring. In this context, high heritability implies a strong resemblance between parents and offspring with regard to a specific trait, while low heritability implies a low level of resemblance. #heritability #populationGenetics #NikolaysGeneticsLessons #genetics #lecture #genes #environment #naturenurture #genotypePhenotype #quantitative #BroadSenseHeritabilityEquation #BroadSenseEquation #crashcourse #science #biology #evolution #heredity #aristotle #bloodlines #gregorMendel #mendelianGenetics #mendelianTrait #classicalGenetics #chromosome #gene #polygenic #pleiotropic #homozygous #phenotype #punnettSquare #reginaldCPunnett #sexlinkedInheritance #autosome
