Abstract—This study was conducted to investigate the correlations among embryo weight, residual yolk sac weight and villus characteristics (villus height, width, and crypt depth) in Gerze and Lohman White genotypes at different embryonic ages. A total of 212 hatching eggs were used from Gerze and Lohman White genotypes. Hatching eggs from each genotype were examined at the beginning of the embryonic day 19 and embryonic day 21 for embryo weight, residual yolk sac weight and villus characteristics. In Gerze embryos, correlation was found only between villus height and villus width on day 19 of incubation period. While, in Lohman White embryos, correlations were found between weight of residual yolk sac and villus width, between villus height and villus width and between villus width and crypt depth on day 21 of incubation period. Genotype and incubation period are important for correlations among these parameters.
