Germline transmission frequency using different transposon vectors

	T2KXIG^a	T2KXIGΔin	T2AL200R200G	T2AL200R150G	T2AL50R50G
Injected fish	10	11	10	10	10
Founder fish^b	5	7	7	6	0
No. of insertions^c	5.6	6.9	6.9	5.5	NA

↵a The result with T2KXIG was described previously (Kawakami et al. 2004b).
↵b The injected fish that transmit the transposon insertions to the F₁ generation.
↵c The average numbers of insertions transmitted per founder fish detected by Southern blot hybridization (Table 2).
