It is written as H2 = VG / Vp and captures the proportion of the phenotypic variation due to genetic values that may include effects due to dominance, recessive, additive, and epistasis.
WebBroad-sense heritability (H2) represents the proportion of phenotypic variance that is due to genetic variance. It is calculated by dividing the genetic variance by the phenotypic … WebBroad-sense heritability, defined as H 2 = V G /V P, captures the proportion of phenotypic variation due to genetic values that may include effects due to dominance and epistasis. …
WebThe broad-sense heritability estimates were 72.6, 72.3, 71.2, 72.3, and 56.1% for SW, SL, TSNS, TKNS, and TKW, respectively. A genome-wide association study (GWAS) was used to identify SNPs associated with yield traits. ... All of these yield-related traits are a little more heritable (h2) than GY, making them simpler to select in small plots ... WebHeritability in broad sense (H 2) is calculated using the following formula : H 2 = S g 2 /S p 2 Therefore, H 2 simply gives a measure of the proportion of phenotypic variance …
