	Gr-JGI	Gr-CGP	Ga-CGP	Gh-Uni	Go-con	mRNA
Gr-JGI	272	249	243	79	28	4
Gr-CGP		255(257)*	236	78	27	4
Ga-CGP			256(259)*	79	28	4
Gh-Uni				79(92)	27	4
Go-con					28(29)	2
mRNA						4(10)

Numbers of non-overlapping paralogous genes from a certain source are shown on the diagonal line with the initial sequence number in brackets. Other numbers indicate overlapped or orthologous genes between two sources.

* The tandem repeat genes encoding identical proteins and orthologous to a single protein from other sources are regarded as a single gene.
