Coupling and Repulsion Hypothesis of Gene

The below mentioned article provides a short note on the Coupling and Repulsion Hypothesis of Gene. Bateson and Punnett in 1906, described a cross in sweat pea, where failure of gene pairs to assort independently was exhibited. Plants of a sweat pea variety having blue flower (BB) and long pollen (LL) were crossed with those of another variety having red [...]

Gene Mapping by Three-Point Test Cross | Cell Biology

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 [...]
