  Turkey hens show spontaneous parthenogenesis (embryo development without any male contribution) which is influenced by genetic and environmental factors. Chromosome pattern and differential expression of genes associated with parthenogenetic development in turkey eggs were investigated in the present study. The metaphase spread obtained from parthenogenetic embryos was classified as haploid, diploid, polyploidy or aneuploidy based on the proportion of ‘n’ number of chromosomes. With the advancement of embryonic age, per cent of haploid cell (38.73 to 20.44) or other ploidy decreased while those of diploid cell increased (21.10 to 42.06) and the transition of ploidy continued till 48 h of embryo dveleopment. Early developmental stages presented higher ratios of W chromosomes in comparison to Z chromosomes while ZW combination was absent. Freshly.. Read More»
