The causal meaning of Fisher's average effect [PDF]

open access: yes, 2013
In order to formulate the Fundamental Theorem of Natural Selection, Fisher defined the average excess and average effect of a gene substitution. Finding these notions to be somewhat opaque, some authors have recommended reformulating Fisher's ideas in ...

Variability studies in Okra (Abelmoschus esculentus L. Moench)

open access: yesElectronic Journal of Plant Breeding, 2016
Sixty genotypes of okra were evaluated in one location for two years at Chatha, Jammu during 2009-10 and 2010-11. The objective was to study the genetic variability between various economically important traits for the purpose of genetic improvement. The
