Figures & Tables

Figure 1

Metaphase spreads of the sea trout (2n = 80) (a), Atlantic salmon (2n = 58) (b) and sea trout × Atlantic salmon hybrid female (c) and hybrid male (d) (2n = 69) after fluorescence in situ hybridization with the fluorescein-conjugated telomere PNA probe. Chromosomes were counterstained with DAPI. Bar represents 5µm.

Cross-sections of gonads of the sea trout and Atlantic salmon hybrids: a – mosaic intersex; b – male at developing stage of maturation, c – male at spawning capable phase, d – female at developing stage of maturation. Descriptions: aca – atretic cortical alveolar oocyte, ca – cortical alveolar oocyte, og – oogonia, ol – ovarian lamellae, sg – spermatogonia, sc1 – primary spermatocytes, sc2 – secondary spermatocytes, sd – spermatids, sl – wall of seminiferous tubule, sz – spermatozoa
