Heterosis and DNA fingerprinting in chickens.
Enhancement of performance in traits of economic importance by use of heterosis (hybrid vigor) is routine in poultry breeding. There is, however, no reliable method to predict the level of heterosis that will occur from the mating of individuals from two populations. DNA fingerprints (DFP) were used as a measure of genetic distance between mating pairs of chickens where each individual of a pair was from a different population; the association between that genetic distance and levels of heterosis in the offspring of those pairs was assessed for juvenile BW and for age at production of first egg. There was an inverse relationship between DFP bandsharing level of parents and heterosis in their offspring, suggesting that DFP may be useful in predicting heterosis.
