In
this study, karyotypic investigation of Steatoda
grossa belonging to the family, Theridiidae was carried out to contribute
cytogenetic relationships of the family. A standard air-drying method was used
to obtain chromosome slides including three main steps as hypotonisation,
fixation and staining. As a result, the diploid number and sex chromosome
system was determined as 2n♂=22 (X1X2). All chromosomes
were telocentric and gradually decreased in size. Sex chromosomes were
positively heteropycnotic in the stages of meiosis I, and isopycnotic in
meiosis II. The results showed the similarity with the previous investigations
obtained from different populations.
