General Statistics for Melon Genes Depending on Orthology and Gene-Density Region Localization

		Gene-Rich	Gene-Poor
Orthologs	Many-to-Many	539 (75.2)	178 (24.8%)
	Many-to-One	855 (83.3%)	168 (16.4%)
	One-to-Many	320 (89.9%)	36 (10.1%)
	One-to-One	12,275 (91.3%)	1,142 (8.5%)
	Other	1,196 (83.9%)	228 (16%)
No Orthologs		3,374 (61.7%)	2,091 (38.2%)
Excluded genes		2,083 (80.4%)	503 (19.4%)
Total		20,642 (82.5%)	4,346 (17.4%)

Note.—Frequency computed per orthology category (rows). Partial genes (i.e., those genes that span both gene-rich and gene-poor region) are not shown. One-to-one: a single gene in melon has a single orthologue in cucumber; one-to-many: a single gene in melon shows orthology to several genes in cucumber; many to one: several genes in melon show orthology to a single gene in cucumber; many-to-many: several genes in melon show orthology to several genes in cucumber.
