WebApr 10, 2024 · Treatment effects on phenotypic traits. First, we tested for the effects of environmental factors (latitude, temperature and predator cue) on each trait separately: wet mass (hereafter, mass), head width, wing pad length, growth rate based on mass (GRM) and growth rate based on body size (GRH) (Table 1).For mass, the three variables, … 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. 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.
