1) Mating opportunity
交配机会
2) random mating
随机交配
1.
And random mating in F2 .
假定给定不同基因型频率的父本F1( m) 和母本F1( w) ,考虑其可能引出的杂交遗传模型,得出了“不管F1 基因型频率分布如何,经过一代杂交、第二代F2 内随机交配,则F3 以后基因型即保持稳定”,同时本文还付给了由Fn 与F1 杂交产生的可能结
2.
A basic(Co) population originated from 72 crosses produced from 75 breeding materials with desired quality and agronomic traits has been synthesized after two times of random mating mediated by a dominant male sterile allele,Ms,in Brassica napus.
以显性核不育基因Ms为异交媒介,用75个具有期望农艺和品质性状的甘蓝型油菜育种材料,配制了含有12种细胞质类型的杂交组合,将这些组合在隔离条件下随机交配2次,合成了供轮回选择用的基础群体(Co)。
3.
We reviewed theoretical and empirical results related to these assumptions,and focused on the recent advances in random mating assumption and presented some new theoretical outcomes resulted from modeling researches.
本文就这3个假设的理论基础和经验研究的进展进行了综合论述,并着重讨论了随机交配假设的最新研究进展以及今后的研究方向和方法。
3) distribution accounting machine
分配会计机
4) switch configuration
交换机配置
1.
Briefed the switch configuration demonstration experiment design of classroom teaching in "computer network engineering" teaching courses ,thus students have a perceptual awareness before the switch configuration and operation, in order to lay a good foundation for follow-up planning VLAN, router configuration etc.
简要介绍了《计算机网络工程》课程实践教学环节中交换机配置的课堂教学演示实验设计,使学生动手做实验之前对交换机的配置和操作有个感性的认识,为后续进行VLAN规划、路由器配置等打下良好的基础。
5) panmixis rate
随机交配率
1.
The higher the panmixis rate is,the faster the population shows tendency to equilibriu.
结果表明,随机交配群体和自交群体是普通群体的两种极端;随机交配率越大群体趋于平衡越快;随机交配率与杂合子频率呈正相关,与纯合子频率呈负相关;随机交配率大于零时,等位基因频率相等,杂合子频率最高;随机交配率等于1/2且等位基因频率相等时,3种基因型频率相等。
6) TXOP allocation
传输机会分配
