In this article we will discuss about:- 1. Introduction to Linkage of Gene 2. Linkage Groups 3. Complete 4. Incomplete. Introduction to Linkage of Gene: Morgan (1910) noted similar behaviour in Drosophila melanogaster (Fig. 8.2) and recorded that coupling and repulsion are two aspects of a single phenomenon called linkage. Morgan was the first to relate linkage to the segregation [...]
In this article we will discuss about:- 1. Introduction to Gene Mapping by Three-Point Test Cross 2. Linkage Mapping Construction 3. Distance and Unit 4. Function. Introduction to Gene Mapping by Three-Point Test Cross: Recombination frequencies are directly proportional to distances between genes in question and these values can be used in preparation of linkage maps. A three-point test cross [...]
