Does triploidization produce functional sterility of triploid males of tench Tinca tinca (L.)?
Original language description
Triploidy interferes with gametogenesis in all aquaculture species tested so far. In fish it results in complete female sterility however males are still able to develop testis. The reason why sterility levels in triploid fishes differ among species andbetween sexes is unclear. In the present study the reproductive potential of triploid males of tench was studied. Analysis of variance showed an insignificant influence of ploidy level on the percentage of motile spermatozoa, as well as on spermatozoa velocity. Experimental crosses between normal diploid female and triploid males resulted in the appearance of triploid progeny, which exhibited genotypes composed of microsatellite alleles inherited from the founder female and additional allele derived from the donor male. We can conclude that the triploid males analysed in the present study were capable to fertilize eggs derived from diploid females.
