Identification of hybrids and new lines of broiler fowls using DNA fingerprints

Custodio, R. W. S.; Coelho, A. A. D.; Savino, V. J. M.

DNA fingerprints from 13 lines of broilers in Brazil were used to identify and evaluate their genetic relationships. Using 5 lines with a low rate of band sharing, it was possible to identify 3 hybrid lines with a good level of heterosis. Using dendrogram analysis from all lines, it was possible to identify 3 groups of 2 lines with an average level of band sharing of >0.73, and in 2 other groups, the average band sharing was above 0.54.
