%X In this study, <i>Enteromius</i> <i>parablabes</i> </span><span>[1]</span><span style=\"font-family:&quot;\"> was analyzed with the aim
of providing baseline information regarding the diploid chromosome number and
karyotype <span>differences of both sexes. The
diploid chromosome number (2n) was 50 for both sexes</span></span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and this corresponds to the diploid chromosome number</span><span style=\"font-family:&quot;\"> <span>reported for most small African <i>Barbus</i> species. The fundamental number</span><span> (NFa) of the male and female was 81 and 98
respectively. The first</span> pair of metaphase chromosome</span><span style=\"font-family:&quot;\">s</span><span style=\"font-family:&quot;\"> which has been suggested
to be a marker for the small African <i>Barbus</i> group was conspicuously larger in the female karyotype. The karyotype of the
female consisted more of metacentric (39m +</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">7sm + 2st + 2t) which is common in the group while
the karyotype of the male which consisted more of telocentric chromosomes (10m
+ 21st + 19T) is scarce. The chromosomal number obtained for <i>E</i>. <i>parablabes </i>demonstrates its diploid status in the context of the ploidy lines
characteristic of the African <i>Barbus</i> assemblage.
