A Bayesian analysis of the effect of selection for growth rate on growth curves in rabbits

Gompertz growth curves were tted to the data of 137 rabbits from control (C) and selected (S) lines. The animals came from a synthetic rabbit line selected for an increased growth rate. The embryos from generations 3 and 4 were frozen and thawed to be contemporary of rabbits born in generation 10. G...
