Phenotypic variance explained
WebOct 1, 2024 · The phenotypic variance explained (PVE) ranged from 1.96% to 30.2% and from 3.08% to 21.63% for yield and plant height, respectively. Among all these 16 QTL, six explained more than 10% of the phenotypic variation. WebMay 16, 2024 · I used the following procedure for estimating the variance explained in R: fit <- lm (Phenotypic_value ~ SNP_data, data = a) summary (fit)$adj.r.squared Here, the datafile a contains three columns namely, sample_ID, Phenotypic_value for each sample, and the biallelic SNP_data.

WebThe phenotypic variance (V P) in a population is influenced by genetic variance (V G) and environmental sources (V E ) V P = V G + V E [7] [8] The total amount of genetic variance can be divided into several groups, including additive variance (V A ), dominance variance (V D ), and epistatic variance (V I ). V G = V A + V D + V I [9]

WebThe total phenotypic variance is thus partitioned : V P = V A + V D + V I + V E. The point of this is that we want to know the additive genetic component of the total phenotypic variance since this is what makes parent and offspring look alike and is what selection can act upon.
