Table 1 The frequency distribution of the 5 different genetic expression patterns of 45S rRNA gene in the F2 hybrids

From: Unique nucleolar dominance patterns in distant hybrid lineage derived from Megalobrama Amblycephala × Culter Alburnus

  Number Percent
Pattern1a 3 10%
Pattern2a 7 23.3%
Pattern3a 13 43.4%
Pattern4a 3 10%
Pattern5a 4 13.3%
Total 30 100%
  1. a Note: Pattern 1 inherits and expresses the single 45S rRNA gene of BSB. Pattern 2 inherits both the 45S rRNA gene from BSB and TC, but only expresses the 45S rRNA of BSB. Pattern 3 inherits and expresses both the 45S rRNA gene from BSB and TC. Pattern 4 inherits both the 45S rRNA gene from BSB and TC, but only expresses the 45S rRNA gene of TC. Pattern 5 inherits and expresses the single 45S rRNA gene of TC
