WebIntergeneric hybrids among the Triticeae have been easy to obtain by utilizing the greenhouse environment and a post-pollination treatment of the florets with gibberellic acid, similar to the procedure of Kruse (1973). Somatic variations in the Fj hybrids are not easily detected, and they generally represent a composition expected by the Web16 de abr. de 2024 · Cetaceans exhibit surprising karyotype uniformity, suggesting that they have a higher potential to produce hybrid offspring than do other mammals [25–27]. However, the identification of cetacean hybrids in the wild is difficult, and the molecular evidence of wild cetacean hybrids is extremely limited [ 28 ].
