2 Main Causes of Ploids (With Diagram)

The following points highlight the two main causes of ploids. The causes are: 1. Aneuploidy 2. Euploidy. Ploids: Cause # 1. Aneuploidy: The individuals carrying chrornosome numbers other than somatic or diploid (2n), which are not true multiples of basic chromosome number or genome are called heteroploids or aneuploids. Thus aneuploidy results due to an addition of loss of less [...]

Variations in Chromosome Number to Plant and Animal

In this article we will discuss about the Variations in Chromosome Number to Plant and Animal.  Every cell in the body of living organism is provided with a packet of genetic material (the nucleus) which contains chromosomes. The number of chromosomes in the nuclei of a given species is fixed. Some species of plants and animals have identical chromosome numbers. [...]

Artificial Induction of Polyploidy

The below mentioned article provides a study note on the Artificial Induction of Polyploidy. In recent years, a number of methods have been worked out to induce polyploidy in plants. Some of them are described below: 1. By Radiation: Polyploidy can be induced in plants by exposing their certain parts, such as vegetative buds and flower buds, to radiations of [...]
