The diagrammatic representation of the relative distance between the linked genes of a chromosome is called linkage or genetic map. Since a linkage map is the outcome of crossing over studies, it is also called crossover map. The method of constructing […]

Deviations from Mendelian Ratio (With Diagram) | Genetics | Biotechnology
Article shared by :
A number of deviations were identified in the post-Mendelian era. The normal monohybrid ratio of 3:1 will occur only when the allele have a relationship of dominance and recesiveness between each other. In the absence of such a relationship, the 3:1 becomes modified variously. Let us understand this with the following examples: 1. Incomplete or […]
