Relative growth rate in sheep: heritability and relationship with absolute growth rate and body weight [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
Data and pedigree information collected between 1990 and 2005 at the Zandi Sheep Breeding Station were used to estimate heritability for relative growth rate (RGR) in five growth phases, namely birth to weaning (RGR1), weaning to 6-month (RGR2 ...

The Pitfalls of Heterosis Coefficients

open access: yesPlants, 2020
Heterosis (hybrid vigour) is a universal phenomenon of crucial agro-economic and evolutionary importance. We show that the most common heterosis coefficients do not properly measure deviation from additivity because they include both a component ...
