Biology. *Summary: [EN] A case of heterozygous development of the satellited chromosome pair of Allium Cepa is described. One of the homologues had a satellite, while the other one had a satellite zone of normal size, but devoid of stainable satellite granule (Fig. 1,2). Division of the satellite granule in preparation of the next nitosis was observed in anaphase chromosomes (Fig. 3) "Joe Hin Tjio (1919?2001), was a cytogeneticist renowned as the first person to recognize the normal number of human chromosomes. This epochal event occurred on December 22, 1955 at the Institute of Genetics of the University of Lund in Sweden, where Tjio was a visiting scientist." Wikipedia
