بررسی جایگاه صفت کمی موثر بر صفات رشد در بلدرچین ژاپنی با استفاده از طرح ناتنی پدری
A paternal half-sib design was implemented to identify QTL on chromosome 2 affecting growth traits in Japanese quail. Using a reciprocal cross between two strains, white (laying) and wild (broiler) of Japanese quail, 34 birds were obtained in F1 generation and 422 offspring related to 9 paternal half-sib families in 5 consecutive hatches were generated. Progeny from 9 paternal half-sib fam...
متن کاملOn the use of linear regression and maximum likelihood for QTL mapping in half-sib designs.
Methods of identification of quantitative trait loci (QTL) using a half-sib design are generally based on least-squares or maximum likelihood approaches. These methods differ in the genetical model considered and in the information used. Despite these differences, the power of the two methods in a daughter design in very similar. Using an analogy with a one-way analysis of variance, we propose ...
متن کاملگزینش برای تحمل به خشکی در فامیل های نیمه خواهری (Half sib family) در چغندر قند
یکی از مؤثرترین روشهای کاهش مقابله با خشکی و افزایش رادمان مصرف آب، اصلاح و تهیه ارقام مقاوم به خشکی است که از تحمل بالایی به خشکی برخوردار بوده و به ازاء یک واحد کاهش مصرف آب، کاهش عملکرد کمتری داشته باشند. بدین منظور اصلاح گردهافشانهای دیپلوئید متحمل به خشکی بهعنوان یکی از پایههای رقم هیبرید مدنظر قرار گرفت. از چهار توده گردهافشان دیپلوئید، تعداد 45 فامیل نیمهخواهری تهیه و در شرایط تنش...
متن کاملSheep linkage mapping: nineteen linkage groups derived from the analysis of paternal half-sib families.
Nineteen linkage groups containing a total of 52 markers have been identified in the sheep genome after typing large paternal half-sib families. The linkage groups range in size from 2 markers showing no recombination to a group containing 6 markers covering approximately 30 cM of the sheep genome. Thirteen of the groups have been assigned to a sheep chromosome. Three groups contain markers fro...
متن کاملCombined line-cross and half-sib QTL analysis of crosses between outbred lines.
Data from an F 2 cross between breeds of livestock are typically analysed by least squares line-cross or half-sib models to detect quantitative trait loci (QTL) that differ between or segregate within breeds. These models can also be combined to increase power to detect QTL, while maintaining the computational efficiency of least squares. Tests between models allow QTL to be characterized into ...
