  • With a combination of detergent-microspreading and silver-staining techniques,the spermatocyte synaptonemal complexes (SCs) of 4 species of macaques I.e.rhesus macaque (M.mulatta),pigtail macaque (M.nemestrina),Assam macaque (M.assamensis),Tibetan stump-tailed macaque (M.thibetana) and a subspecies of rhesus monkey (M.m.lasiota) were observed by electron microscope.The results demonstrate the high similarity of SC karyotypes as well as its development among these macaques.The autosome synapsis or pairing of autosomal lateral elements starts at early zygotene,completes at pachytene and disppears at diplotene.Five types of XY pairs have been described,on the basis of patterns of XY pair.The morphology of XY axes and homology of X and Y were discussed also.
