AbstractThis study was carried out at the Ruminants Researches Station /State Board for Agriculture Researches / Ministry of Agriculture, Reproductive laboratory in college of Agriculture/Univ. of Baghdad & Technical Center of AL-Nahrain Univ. over period from 1/1/213 until 1/6/2014. The aim of this study was to find the genotypes (polymorphism) of Cyp19 gene and relationships of these genotypes with reproduc tive performance and growth in Turkish Awassi sheep. The distribution percentage of polymorphism of Cyp19 gene in sheep sample study were 8.75 , 58.75 & 32.50 % for AA, AB & BB genotypes respectively, with significant differences between them.the result showed that genotype had a significant effect on fertility and highly significant(p<0.05) on prolificacy, but had no significant effect on birth weight and gain from birh to weaning. Conclusion from study of gene expression of Cyp19 gene, can
applied on improvement strategy of sheep to increase the reproductive & growth performance in breeding station.
