Two populations of breeding stock with desired characteristics are subjected to inbreeding until the homozygosity of the population exceeds a certain level, usually 90% or more. The divergence between the (two) parent lines promotes improved growth and yield characteristics in offspring through the phenomenon of heterosis ("hybrid vigour" or "combining ability"). The offspring showed a combination of the phenotypes from each parent that were genetically dominant. Some sources state that the goldfish (Carassius auratus) is a cultivated breed of crucian carp taken from the wild..
