    • Abstract
  • The diploid chromosome number of hybrid F1 between Swamp and Murrah buffalo is 49.It is known that the chromosomal banding pattern of the two forms of buffalo are quite similar.No.1 chromosome of Swamp may result from a telomere-centromere tandem translocation between No.4 and No.9 chromosomes in the Murrah karyotype.In order to confirm this explanation the synaptonemal complex in spermatocytes of F1 hybrid has been examined by electron microscopy.At pachytene,22 autosomal SCs,an metacentric/submetacentric/telocentric trivalent and an XY pair were observed.Our results indicate that No.1 chromosome of Murrah could be result of a tandem translocation.There is high chromosomal homology betweem the two buffalos.
