Cytogenetic analysis of a Mediterranean Gobiid fish Gobius paganellus L., 1758 from Turkey

In this study, cytogenetic analysis of Gobius paganellus, a Mediterranean Gobiid fish from the southern coast of Turkey, was carried out by modified air-dried technique. Phytohemaglutinine pretreatment was performed before the conventional air-dried technique to increase the mitotic index. Chromosomes were obtained using gill tissue. As a result, it was determined that the diploid chromosome number of Gobius paganellus is 2n = 44 (NF = 45), comprising one large metacentric and 43 acrocentric chromosomes.
