| dc.description.abstract | The aim of this thesis was to determine whether the genome size (diploidy vs. triploidy) of a sterlet (Acipenser ruthenus) could affect the number and density of cells housed in their brains.
In order to determine this correlation, we quantified the total brain cell counts and neurons using the Isotropic Fractionation. We then compared the values of 2n males, 2n females, 3n males and 3n females to determine whether a combination of ploidy and sex yielded higher brain cell counts. | cze |

| dc.description.defence | <p>Dr Štěrba welcomed the student and commission members; all members of the commission were present; the supervisor was not present and was connected via a TEAMS meeting. The student presented the theoretical background of his work on sexual dimorphism in fish, brain. Then the student presented the methods used and the results for the various parts of the thesis, followed by conclusions.</p>
<p>The supervisor, Dr Němec, and the opponent, Dr Gazo, presented their reviews. The student answered all the questions of the opponent and also questions from the commission members and the audience on the relevance of sterility of triploids and the effect of triploidy on other organs except the brain, the antigen of neuron-specific antibody, and on the existence of a new hypothesis, which could be tested.</p>
