"It is dishonest to suggest, or imply, that BLUP (EPD) analysis will allow accurate genetic comparisons of all economically important traits across all environments. A trait such as fertility is determined by hormonal balance (largely unaffected by environment) and body condition (largely a reflection of environmental adaptation). It is therefore subjected to genotype X environment interaction. Animals performing well in one environment may perform poorly in a different environment. This is reflected in fertility. No mathematical model can correct for this in order to allow animals be compared across environments with regard to traits that are subjected to genotype X environment interaction." Johann Zietsman From: Man - Cattle - Veld, A Ranching Revolution: To be published later this year.
