41. Triploid female salmon have highly atrophied ovaries and, unlike triploid males, don't attempt to mate. 42. The triploid cytotype probably originated in the Himalayan region, as a hybrid between the diploid and tetraploid cytotypes. 43. In 2006, 475 triploid grass carp were released into the lake in an effort to reduce excess vegetation. 44. AquaBounty indicates their GM salmon can not interbreed with wild fish because they are triploid which makes them sterile. 45. Since the triploid specimens bore abortive spores, it was apparently the hybrid between the diploid and tetraploid groups. 46. The cultivar is compatible with most rootstocks, but its pollen quality is poor because it is a triploid . 47. In both cases, diploid hybrids generate also not reduced diploid gametes ( RL ) needed to recreate triploids . 48. Diandry appears to predominate among early miscarriages, while digyny predominates among triploid zygotes that survive into the fetal period. 49. According to Thompson the primary spadix during flowering, and tendency of the leaf margin to undulate in the triploid . 50. They are triploid in origin, containing one set of maternal haploid genes and two sets of paternal haploid genes.
