There are many ways of cloning a disease gene, depending on what is known about the disease. We will show several typical examples in this part of the lecture

个体发育复杂 多层次 ·无衰减子 受环境影响较小

多细胞动物的胚胎发育比较复杂。不同类的动物,胚胎发育的情况不同,但是早期发育 的几个重要阶段是相同的

F and partial diploids The F-factor in a Hfr chromosome can excise out to become an autonomously replicating plasmid If a segment of the chromosome becomes part of the F pp lasmid during excision, the new element is called an F plasmid

一、概念：重复；缺失；倒位；易位；假显性；假连锁；交换抑制因子；Schultz-Redfield效应；平衡致死系；染色体组；单倍体；二倍体；多倍体；单体；缺体；三体；四体；双三体

《动物生物学》课程教学资源（PPT课件讲稿）动物体的生命活动

1 分离规律、自由组合规律的定义,遗传现象, 表现形式和实质 2 实现孟德尔分离比的条件 3 用分枝法对多基因杂种进行遗传分析

1 题解: 名词解释 P163 2 题解: 据题意 10/200=5% 3 题解: 据交换值愈大，两个基因在染色体上相距愈

About the final It will be in English. Try to answer in English as well. The problems are given in such a way that very short answers are needed. Chinese allowed if you can only read English

Bacterial Genetics Key Requirements Understand how genetic mapping is achieved in bacteria: Co-transformation, F factor Hfr strain co-transduction and some understanding of phage genetics 2. Read the textbook and do the problem set at the back
