Abstract

There
are 55 species of agelenid spiders in our country and the genus Tegenaria represents the widest group in
terms of species number. In
this study, it was aimed to investigate the cytogenetic properties of Tegenaria elysii species. Chromosomes
were obtained by making some modifications to the method of Pekár and Král
(2001). Hypotonic, fixation and staining steps were applied to the gonads
respectively. As
a result, the number of diploid chromosomes and the sex chromosome system were
found as 2n=42, ♂X₁X₂0/♀X₁X₁X₂X₂.
Total relative lengths of chromosomes decreased gradually from 6,83%
to 3,31%. Sex
chromosomes which positive heteropycnotics in the stage of meiosis I have been
detected to be isopycnic in the stage of meiosis II. 20 autosomal bivalent and
two sex chromosomes were identified in which diplotene and diakinesis stages.
