f1 generation meaning in Chinese
(f1代)：两个亲本系(同源)杂交后的第一代。
Examples
- F2 the second filial generation , obtained by crossing or selfing within the f1 generation
子二代（杂种二代） ： ，通过子一代内部的杂交或自交获得。 - Effects of perinatal exposure to bisphenol a on the growth and development of brain of the f1 generation of male sd rats
暴露对雄鼠子一代生长和脑发育形态的影响 - The yields of the several two - line hybrids and traits between normal plant and male sterility plant of f1 generation of hybrid flax were investigated
摘要通过田间试验，对几个利用温敏雄性不育亚麻雄性不育系配制的杂交种的产量表现及不育株率和不育株率对产量的影响进行了分析。 - With respect to genetic similarity , genetic distance and cluster analysis among samples of f1 generation , it showed that the most genetic identity is between jfp and jmp , ( i = 0 . 9934 , dnei = 0 . 0066 ) , the next was between jp and jmp ( i = 0 . 9873 , dnei = 0 . 0128 ) , the third was jp and jfp , with i = 0 . 9681 , dnei = 0 . 0325 ; the fourth was jp and cp , with i = 0 . 9035 , dnei = 0 . 1015 ; the fifth was cp and jmp , with i = 0 . 8862 , dnei = 0 . 1208 , and the furthest was between cp and jfp , with i = 0 . 8648 , dnei = 0 . 1452
由此可以看出在此四组中，杂交组的遗传变异明显高于自交组的，杂种优势已初步显示出来。而在两杂交组中，日雄中雌杂交组又优于日雌中雄组中自交组。群体间遗传相似系数和遗传距离及聚类分析结果表明：两杂交组间的遗传相似系数最大，遗传距离最小，仅为0 . 0066 ，而中自交组群体与日雌中雄杂交组群体的遗传距离最大为0 . 1452 ，两自交组群体间的遗传相似系数为0 . 9035 ，遗传距离为0 . 1015 。 - The results show that the genetic diversity of filial generations is higher than self - bred progeny ’ s ， the hybrid vigor has manifested at metabolization level 。 the proportion of polymorphic loci ( p . 99 ) in f1 generations was 30 . 77 - 36 . 36 % ， the mean observed heterozygosity ( ho ) of jmcf （ japanese male chinese female ） was the highest with 0 . 1727 , the rest populations were ： jfcm （ japanese female chinese male ） 0 . 1536 、 cp 0 . 1273 and jp 0 . 1055 ， the mean effective number of allels per locus in f1 generations ： cp ’ s was the highest with 1 . 7318 ， jp ’ s was the lowest with 1 . 6718 ， the filial generations ’ values were in the midle of the cp ’ s and jp ’ s and between them there was no brightly difference , with 1 . 6955 ( jfp ) and 1 . 6927 ( jmp )
各组的平均杂合度预期值也表现出该趋势，即：日自交组最低，为0 . 1786 ，日雄中雌杂交组的平均杂合度最高，为0 . 1964 ，日雌中雄杂交组和中自交组分别是0 . 1891和0 . 1865 。 hardy - weinberg平衡下遗传偏离指数也是杂交组的小于自交组的，平均每个位点的等位基因有效数目中自交组最高为1 . 7318 ，日自交组最低为1 . 6718 ，两杂交组群体的这一指数相差不多，分别是1 . 6955和1 . 6927 ，位于两亲本的中间水平。
