Table 1.

The distribution of gene numbers in tandem arrays from three sub-genomes of Brassica rapa after whole genome triplication (WGT).

	LF	MF1	MF2	Total
0 gene	88	137	173	398
1 gene	141	144	133	418
>1 genes	185	133	108	426
Total	414	414	414	1,242

“0 gene” refers to the genes in the tandem arrays of the B. rapa’s ancestor that were all lost in the sub-genome of B. rapa.

“1 gene” refers to the genes in the tandem arrays of the B. rapa’s ancestor that were fractionated to a single gene in the sub-genome of B. rapa.

“>1 genes” refers to the tandem arrays of the B. rapa’s ancestor that were maintained in the sub-genome of B. rapa.
