Abstract—Heritability allows comparing the relative contributions of genes and environment to trait variation both within and between populations. Geneticists and plant breeders frequently use heritability as a measure for how is accurate a trial or set of trial. Sewall Wright and Ronald Fisher established the idea of heritability almost a century ago, defining it as an estimable, dimensionless population quantity. Heritability is still essential to the response to selection in evolutionary biology and agriculture, particularly in plant breeding, despite ongoing misconceptions and disputes regarding its usage and application. The importance of heritability in the genomics era is demonstrated by recent reports of significant heritability for gene expression and novel estimation techniques utilizing marker data. Understanding the common misconceptions surrounding the use of heritability is crucial to minimize confusion during selection in plant breeding.
