To identify their sexes by their apparent morphology is difficult. Such characteristic complicates the research on establishing breeding program and conservation for these animals. Therefore, the objective of this study was to investigate sex-specific genetic markers of Crested Serpent Eagle and Collared Scops Owl using random amplified polymorphic DNA (RAPD) fingerprinting.e used sex-specific primers of avian CHD1 (chromo-helicase-DNA-binding 1) gene and EE0.6 (EcoRI 0.6-kb fragment) sequence to identify these five birds sex. Besides, 120 random primer sequences were from RAPD 10 mers kits (Operon Biotechnologies) and used for RAPD fingerprinting to search for sex-specific fragments of Crested Serpent Eagle and Collared Scops Owl. he results showed that CHD1 gene could correctly identify sex in Crested Serpent Eagle and Grass Owl only. Furthermore, EE0.6 sequence could also correctly distinguish sex of these birds, the useful primers sets are A, C and D for Crested Goshawk; E. primers sets for Collared Scops Owl and Tawny Fish Owl; C、D and F for Grass Owl. Moreover, The RAPD results showed that OPBB08 and OPAT15 random primers generated approximately 1.2 and 1.3 kb sex-specific fragments in female Crested Serpent Eagle and OPAN15 random primer generated a 1.3 kb sex-specific fragment in female Collared Scops Owl. The sex-specific fragments were constructed into the vectors for sequencing. According to the sex-specific fragments sequences, several primers were designed for sex identification in 41 Crested Serpent Eagle and 16 Collared Scops Owl respectively. The CseBB08-5a (Crested serpent eagle BB08-5a) and CseBB08-5b primers amplified 553 and 895 bp fragment respectivily in all female Crested Serpent Eagle but not in the male; the CseBB08-7 primers amplified a 194 bp fragment in all female Crested Serpent Eagles and a 543 bp fragment in all females and males; the CseAT15 primers amplified a 734 bp fragment in all female Crested Serpent Eagle and a 147 bp fragment in all females and males. The CsoAN15-6 (Collared scops owl AN15-6) primers from Collared Scops Owl genomic sequences amplified a 349 bp fragment in all female Collared Scops Owl and a 796 bp fragment in all females and males. The common amplified fragment in both male and female birds can be used as an internal control. In addition, we tested those primers on other species and found that CseBB08-5b of Crested Serpent Eagle could also be used for sex identification in Crested Goshawk.n this study, we have identified novel sex-specific DNA markers of Crested Serpent Eagle, Collared Scops Owl and Crested Goshawk. The use of these sex specific DNA markers would help in correctly identifying sexes before matching pair in a captive environment.謝誌 I錄 II次 IV次 V文摘要 VI文摘要 VIII獻探討 1、 鳥類之基因組 (genome) 與性染色體 (sex chromosome) 1、 單態性 (monomorphic) 鳥類之性別鑑定方法 2、 形質測量值 (morphometric measurements) 和體色 (color) 差異 2、 聲紋分析 (acoustic analysis) 3、 泄殖腔性別鑑定法 (vent sexing) 3、 腹腔內視鏡性別鑑定法 (laparoscopy) 4、 性類固醇內泌素鑑定 (hormone analysis) 5、 遺傳分子性別鑑定 5、 大冠鷲、領角鴞、鳳頭蒼鷹、黃魚鴞和草鴞之概述 13、 大冠鷲 (Crested Serpent Eagle) 13、 領角鴞 (Collared Scops Owl) 13、 鳳頭蒼鷹 (Crested Goshawk) 14、 黃魚鴞 (Tawny Fish Owl) 14、 草鴞 (Grass Owl) 14、 研究目的 15料與方法 18、 試驗動物 18、 基因組 DNA 之萃取及定量 18、 試驗動物性別確認 19、 RAPD 指紋鑑定 22、 性別特異性片段回收與選殖 22、 性別特異性引子設計與 PCR 擴增 24、 以性別特異性引子鑑定黃魚鴞、鳳頭蒼鷹與草鴞性別 24果 26、 以 CHD1 基因進行性別鑑定 26、 以 EE0.6 序列進行性別鑑定 28、 以 RAPD 指紋分析進行鑑定 32一) 大冠鷲 32二) 領角鴞 45、 以性別特異性引子鑑定鳳頭蒼鷹、黃魚鴞與草鴞性別 52論 53、 CHD1 基因性別鑑定 53、 EE0.6 序列性別鑑定 54、 RAPD 指紋分析性別鑑定 56一) 大冠鷲 56二) 領角鴞 58、 以性別特異性引子鑑定鳳頭蒼鷹、黃魚鴞與草鴞性別 59論 60考文獻 61錄 68application/pdf2717401 bytesapplication/pdfen-US性別鑑定逢機增殖多態性 DNACHD1 基因EE0.6 序列大冠鷲領角鴞鳳頭蒼鷹sex identificationrandom amplified polymorphic DNA (RAPD)Crested Serpent EagleCollared Scops OwlCrested Goshawkthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182037/1/ntu-97-R95626003-1.pdf
