Plants of a sweat pea variety having blue flower (BB) and long pollen (LL) were crossed with those […]
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 […]
