Allogeneic testes transplanted into partially castrated adult medaka (Oryzias latipes) can produce donor-derived offspring by natural mating over a prolonged period

Table 4 Results of the mating analysis at 13 weeks or more after surgery: surrogate father of d-rR strain allografted with actb-GFP strain or wild-derived strain testis

After surgery (weeks)	13	13	13	15	13	13
Individual	#1 or #4^a	#1 or #4^a	#3	#6	#7	#8
GFP + or pigmented eggs	0	0	15	97	86	20
GFP—or non-pigmented eggs	94	17	69	0	0	106
%	0.00	0.00	17.86	100.00	100.00	15.87

Males of d-rR strain were used as recipients. The genetic backgrounds of donor testis were as follows; #1 ~ #4, actb-GFP; #6, npba-GFP; #7 and #8, wild-derived strain. ^a#1 or #4 could not be distinguished
