亲代全称是： parental generation ，所以用“P”表示 子代的英文是： Filial generation 所以子一代用F1表示；子二代用F2表示F是first generation的意思，就是第一代的生物个体。filial generatiionn表示杂种后代filial generationfilial generation

P表示亲代，F表示子代，其中F1为子一代，F2为子二代，以此类推。这是遗传图解中的基本表示符号，英文中亲代译为Parental generation;子代译为Filial generation.取英文首字母即为P和F。话说 这些生物书上写的都有P指的是亲本F指的是子代F1是子一代 F2是子二代 以此类推参考资料：自己亲代P是...
【答案】亲本;子一代;子二代;杂交;杂交;母本;父本【解析】杂交实验过程与实验中相关符号及含义:亲本英文为parent,遗传学和育种工作上常用符号P表示。子代的英文是: Filial generation ,所以子一代用F1表示;子二代用F2表示。参与杂交的雄性个体叫父本,用符号♂表示;参与杂交的雌性个体叫母本,用符号♀表示。...
P generation is the parental generation. This generation is the first in any genetic cross pollination experiment. These parents should be true bred so that their alleles are known. F1 generation is the first generation of offspring produced by the P generation. F2 generation is the generation th...
The next row(F2 generation), shows us the offspring numbers of a male and female from the F1 generation. Those numbers give us a ratio of 1:1:1:1 of 1 wild male to 1 yellow male to 1 female wild to 1 female yellow. This tells us that there is around the same amount offspring ...
A previously characterized pattern of degeneration of the olfactory epithelium that lines the dorsal septum and dorsal and medial aspects of the nasal turbinates occurred in the F0 and F1 generation animals from the 500-ppm group. In the 500-ppm group, F2 birthweights were reduced compared to ...

Intact L1s genes encode ORF1p and ORF2p within single, bicistronic RNAs (L1 ORF1p carries the cognate gene symbol L1RE1 in UniProt; L1 ORF2p has not been assigned a recommended gene symbol in UniProt). These proteins have been shown to preferentially bind to the L1 RNA that encodes them...
数学上,我们可以将数据概念视为一系列语义实例的集合D,其中每个语义实例d∈D都被识别为具有相同的语义属性集S。这里的S={f1, f2, ... , fn},可以被视为一组定义数据概念语义特征的参数,其中fi表示数据概念的一个语义特征。这种表述有助于我们理解数据概念是如何基于共享的语义特征被归纳和处理的。
