[ 3 ] - مقایسه روش های آماری پارامتری و بازنمونه گیری در ارزیابی صفات کمّی با ساختار ژنتیکی متفاوت
هدف از این مطالعه مقایسه سه روش پارامتری (GBLUP، BayesB، RKHS) و دو روش بازنمونهگیری (Bagging GBLUP و Random Forest) در پیش بینی ارزشهای اصلاحی ژنومیک برای صفاتی با ساختار ژنتیکی متفاوت بود. یک ژنوم با سه کروموزوم، هر کروموزوم به طول یک مورگان شبیهسازی شد و روی آن 1500 نشانگر تک نوکلئوتیدی (SNP) در سه سناریو 50، 100 و 200QTL به طور یکنواخت پخش شدند. اثر جایگزینی QTLها با استفاده از توزیع نرم...
