Figure 5From: Transcriptome analysis of extant cotton progenitors revealed tetraploidization and identified genome-specific single nucleotide polymorphism in diploid and allotetraploid cottonIdentification and characterization of Genome-specific single nucleotide polymorphism (GNPs) between diploid cotton GaA and GrD. (A) Frequencies (Y-axis) of the distance to adjacent GNPs, which was not evenly distributed. Over 70% of GNPs were biased in a range from 100- to 600-bp. (B) Frequencies (Y-axis) of all possible types of transversion and transition (X-axis).Back to article page
