The role of chromosome heteromorphism in developmental anomalies,chromatic regions, especially the short arm and satellite regions of the acrocentric chromosomes and the long arm of the Y chromosome. The advent of new staining techniques has helped in the identification of sites of morphological variation in human chromosomes. The variable segments correspond to

Embryonic development in patients with a high risk of early pregnancy loss,abnormal development of the aborted conceptus in these cases has been well documented since the time of Mall in 1908. who also observed that the frequency of anomalies is directly proportional to the developmental age of the conceptus. In the aborted embryo the incidence is over 80%, declining throu

Effect of chromosome changes on body and mind development,hodology of study was described and the correct chromosome number of our species established. The new techniques that developed soon afterwards opened a whole new field in human biology, in relation to both normal and abnormal variation. Up to 1970 several new syndromes had been delineated, the aeti
