Mean DNA content in GC, BSB, and 2nGB and 3nGB hybrids

Fish type	Mean a DNA content	Ratio
		Observed	Expected
GC	60.56
BSB	74.55
2nGB	68.63	2nGB/(0.5 GC + 0.5 BSB) = 1.02b	1
3nGB	98.19	3nGB/(GC + 0.5 BSB) = 1.00b	1

^aThe intensity of fluorescence (unit, channel).

^bThe observed ratio was not significantly different (P > 0.05) from the expected ratio.
