KIL FOLİKÜLÜ GELİŞİMİ ÜZERİNE ETKİLİ GENLER

Molecular studies have come to the fore within the scope of the development of animal breeding. For this reason, genetic studies made or will be made on production and quality of hair in animals have become more of an issue. In animals like goat and sheep been rich in terms of textile products, hair structure is constitutively divided into two as primary and secondary. In studies made in these follicles, it is identified that the 10077 genes are expressed in the primary hair follicles and the 7772 genes are expressed in the secondary hair follicles. In this review, it will be summarized the anatomy and the process of development of the hair follicle generating the animal fibers, genes had an effect upon development of hair and the processes formed the hair follicle of these genes. In addition, it will be mentioned about structure of hair follicle and efficiency of genes; morphogenesis and cycle stages; anagen, catagen and telogen. The scope of this work includes examination of genes associated with quality from the formation of hair follicle to starting of first cycle and in the repetition of process continually.
