Procedure for generating the reciprocal cross hybrids of BSB and TC. (A) BSB. (B) TC. (C) BTF1 of BSB (♀) × TC (♂). (D) BTF2 produced by intercrossing within BTF1. (E) BTF3 obtained by intercrossing within BTF2. (F) TBF1 of TC (♀) × BSB (♂). (G) BTF2 produced by intercrossing within TBF1. (H) TBF3 obtained by intercrossing within TBF2. The images of the fish hybrids are only representative of certain progeny. (Scale bar) 3 cm.
