After staining with the BSG technique for constitutive heterochromatin, human polymorphs exhibit chromocentres which are presumably derived from these chromosomal regions. In five individuals having an extended centromeric heterochromatin region on one No. 1 chromosome, a particularly large chromocentre was seen in the majority of polymorphs. Thus, prominent chromocentres in polymorphs may indicate the presence of constitutive heterochromatin variants.
在用BSG技术对组成型异染色质进行染色后，人类多形核细胞呈现出染色中心，这些染色中心可能源自这些染色体区域。在五个个体中，其中一条1号染色体上有一个扩展的着丝粒异染色质区域，在大多数多形核细胞中都观察到一个特别大的染色中心。因此，多形核细胞中明显的染色中心可能表明存在组成型异染色质变体。
