The numerical changes percentage is higher than structural changes percentage in, FI, Fj and Fs birds. The chromosomal changes
percentage were the higher in treatments (air sac, embryo and combined effect) than control birds. Haploid percentage showed highest numerical changes in all groups than monosomic, dimonosomic, tetrasomic and triploid percentages. The centromeric
attenuation percentages showed the higher in structural types in all groups than break percentages. The highest chromosomal change percentages were through with ducks DNA among GH gene in embryos, air sac and combined effect. The highest chromosomal changes percentage was through injection ducks DNA than GH gene in all treatments; embryos, air sac and combined effect. The highest chromosomal changes percentage was through injection ducks DNA than GH gene at 20 jag/egg than 10 ug/egg and combined effect for 5.0 minutes than 2.5minutes exposure period. The highest chromosomal changes percentage was in FI among all generations examined (FI, F2 and F3 birds.
