what does it mean when the narrow sense heritability is 2.7
Narrow sense heritibility means any variation occured in a progeny/generation because of additional genetic factors. It includes only additional genetic variation (total phenotypic variation) which are mostly predictable in nature.
The inherited genes contribution to most of the genetic based variance of the population is 2.7 and the rest is phenotypic variation in narrow sense heritibility.
