常見例句When a dihybrid is selfed, a characteristic dihybrid ratio of 9:3:3:1 is obtained in the offspring. 用這個(gè)雜合子自交后,后代性狀分離的比率為9:3:3:1。Such interactions between genes lead to apparent deviations from the 9:3:3:1 dihybrid ratio in the F2. 這樣的基因之間的關(guān)系使得它們的F2代的孟德爾比率偏離9:3:3:1。If the characteristic is governed by simple Mendelian genes, the typical monohybrid and dihybrid ratios become apparent in the F2 generation. 如果其特征取決于單一孟德爾基因,那么典型的單基因雜種和和雙基因雜種的遺傳比率將在子二代呈現(xiàn)。allele dihybrid crosses 等位基因二雜種雜交dihybrid cross 雙因子雜種雜交dihybrid modified 修飾雙因子雜種 返回 dihybrid
