Üreme Mevsimi Dışında Kazak Koyunlarının Üremeleri Üzerine İnhibin-βA Geninin Etkisi

İnhibin-βA (INHBA), folikül stimule edici hormon (FSH) sentez ve salınımını baskılayabilir ki bu durum koyunlarda yavru sayısı ile ilişkili olabilir. Bu çalışmada, inhibin-βA geni aday gen olarak değerlendirilerek Kazak koyunları çalışma materyali olarak kullanıldı. Genin polimorfizmi PCR-SSCP metodu ile belirlendi ve yavru sayısı ile ilişkisi analiz edildi. Elde edilen sonuçlar, Kazak koyununda ekzon 5’UTR bölgesinde AA, AB ve BB için üç polimorfizmin bulunduğunu gösterdi (primer 0-2). Korelasyon analizi, Kazak koyununda genotip AA’da 0.13 kuzu bulunduğunu (P

Effect of Inhibin-βA Subunit Gene on Reproductive Performance of Kazakh Sheep in Non-breeding Season

Inhibin-βA (INHBA) could feedback suppress synthesis and secretion of follicle-stimulating hormone (FSH), which correlates with the litter size ofsheep. In this study, the inhibin-βA subunit was used as a candidate gene, and Kazakh sheep was used as a test object. The polymorphism of thegene was detected by PCR-SSCP method and its association with litter size was analyzed. The results showed that there were three polymorphismsin the exon 5’UTR region (primer 0-2), for which AA, AB and BB were detected in Kazakh sheep. The correlation analysis showed that genotype AAhad 0.13 (P
