The following points highlight the three main importance of chromosomal aberrations. The importance are: 1. Role in Evolution 2. Role in Genetic Analysis 3. Role in Plant Breeding. Chromosomal Aberrations: Importance # 1.Role in Evolution: The study of the karyotypes of different species has revealed interesting facts about the plant kingdom. It has been demonstrated that individuals in wild populations [...]
In this article we will discuss about the Introduction and Present Status of Genetic Evolution of Species. Introduction to Genetic Evolution of Species: The concept of 'organic evolution' envisages that all the living forms of today developed from a common ancestor. That is, the various life forms are related by descent, which accounts for the similarities among them. The idea [...]
The below mentioned article provides a close view on the Polyploidy and Evolution of Species. The polyploidy has played an important role in evolution of new varieties and species in nature. Angiosperms and Pteridophytes have very high numbers of polyploid species in nature. More than 35 per cent angiosperms are polyploids. According to Manton (1950), among all the plant groups, [...]
