  1. A formula a(b) + c(d) was used to described the rDNA pattern. a indicates sites number of 5S rNA or 45SrDNA which shared a common chromosome each other; b indicates number of chromosomes carrying both 5S rNA and 45SrDNA; c indicates sites number of 5S rNA or 45SrDNA which are solely located; c indicates number of chromosomes carrying solely 5S rNA or 45SrDNA
