AU - 1Raaed Abdul Rahman Saeed Ali, 1Raaed Sami Attee, 2Aseel Ghazi Radhi PY - 2022 VL - 14 IS - 4 SP - 253 EP - 261 JO - Euphrates Journal of Agricultural Science مجلة الفرات للعلوم الزراعية SN - 20723857 AB - This study was conducted in the central of health laboratory/ Animal and Fish Resource Research Center / Agricultural Research Department / Ministry of Science and Technology, for the period from 15/8/2021 to 15/11/2021 with the aim of investigating in polymorphism the Growth Hormone-1 Gene GH-1 and its relationship to a number of physiological traits (total protein, albumin and cholesterol) of Cyprinus carpio L. In 90 fish representing three different ecosystems (30 fish for each site), including floating cages, ponds, and the Tigris River south of Baghdad. The polymorphisms of the growth hormone gene were investigated using Single-Stranded Conformation Polymorphism (SSCP) and polymerase chain reaction (PCR).blood was taken from the caudal vein of each fish, and to extract DNA in addition to measuring , albumin and cholesterol.genotyping of samples by SSCP analysis showed six different banding patterns including A,B,C,E, F, and H with a frequency of 24.4, 5.6, 15.6, 15.6, 16.4, and 22.4, respectively, for a population of fish in the studied sites. The H Pattern was associated with the highest rate of protein concentration (4.05±0.11), and the same Pattern recorded the lowest rate of albumin and cholesterol (0.68±0.07) and (146.7±21.3), respectively.
