Abstract :

در این مطالعه به منظور بررسی چند ‌شکلی ژن هورمون رشد به ‌عنوان یک ژن کاندیدا، نمونه‌های خون به‌ طور تصادفی از 34 بز نژاد آلپاین و 42 بز نژاد سانن به‌ دست آمد. DNA از نمونه‌های گرفته شده استخراج و ناحیه 365 جفت بازی از اگزون 5 ژن هورمون رشد توسط واکنش زنجیره‌ای پلی‌مراز تکثیر شد. محصولات PCR توسط روش SSCP بر روی ژل پلی اکریل آمید مورد آنالیز قرار گرفتند. نتایج آنالیز نشان داد که برای ژن مورد مطالعه چهار الگوی باندی متفاوت G1، G2،G3  و G4 به‌ ترتیب با فراوانی‌های 38/0 ،21/0 ،23/0 و 18/0 در بز آلپاین و 48/0، 21/0 ، 17/0 و 14/0 در بز نژاد سانن مشاهده شدند.
