Upload NowA 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 […]

In this article we will discuss about the definition of pleiotropy. Also learn about some examples of pleiotropy. The ability of a gene to influence more than one phenotypic trait is known as pleiotropy. However, of the many effects, one effect is more pronounced than the other and is called the major effect, while the […]
