Witryna1 lip 2014 · The characters were less influenced by the environment thus the traits can be used for selection. Heritability was greater than 80% for all characters studied whereas expected genetic advance ranged from low (8.91) in days to silking to high (72.03) in number of ear per plant. ... High heritability and high genetic advance for ASI … WitrynaThere are four types of gene action: additive, dominance, epistatic, and overdominance. 1. Additive gene action. The effect of a gene is said to be additive when each additional gene enhances the expression of the trait byEqual increments. Consequently, if one gene adds one unit to a trait, the effect of aabb = 0, Aabb = 1, AABb = 3,and AABB = 4.
