Zübeyde Kumbıçak1,* and Hatice Poyraz2
Karyotypes of male Drassodes species from mitotic metaphases; 2n♂=22 (X1X20). A, Drassodes bifidus; B, Drassodes serratichelis. Bars=10 µm.
Meiotic stages of Drassodes bifidus: A, diplotene; B, diakinesis; C, anaphase I - Drassodes serratichelis; D, pacyhtene; E, diplotene; F, anaphase II (black arrows indicate sex vesicle or sex chromosomes. Black arrowhead indicates chiasma with two chiasmata, white arrowhead indicates ring bivalent and asteriks indicate nuclei with 2n=12 chromosomes). Bar=10 µm.
