Non-motile tetraploid spermatozoa of Misgurnus loach hybrids

Abstract: We have compared various properties of spermatozoa from the wild diploid male pond loach Misgurnus anguillicaudatus to those from the interspecific male hybrid of the cross between a female M. anguillicaudatus and a male mud loach M. mizolepis. Our results show that spermatozoa from this interspecific hybrid had poor motility, low viability, abnormal morphology, a larger volume of mitochondrial mass per cell and higher ATP content of spermatozoa with tetraploid DNA content, and they were present at a low conce… Show more

“…As mentioned above, C. taenia hybrids are closely related to the species used in this study, but it could not be a comparison due to the lack of studies on their motility characteristics. However, the Misgurnus hybrids belonging to the Cobitidae have shown that their hybrids also have quite low concentrations and total motility in contrast to that of the bisexual species (Zhao et al, 2016). But, these results are considerably different from our study, which showed partially prominent sperm motility, especially in the HHL type.…”

“…longicorpa hybrid males is also predictable. Nevertheless, in the present study, one type of hybrid (HHL) had an exceptionally higher value for sperm motility (13.6%) compared with other types of hybrid species (HL and HLL, almost 0%) and infertile male in Misgurnus hybrid belonging to the same family of Cobitidae (less than 5%) (Zhao et al, 2016), although the motility of HLL hybrid was distinctly lower than the bisexual species (C. hankugensis, 91.3%; I. longicorpa, 87.5%). Even though the motility of hybrid males was minimal, some showed clear motility, which is inconsistent with the sterility estimated by the histological and cytogenetical observations discussed earlier.…”
