POLYPLOIDISATION Meaning and
Definition
-
Polyploidisation is a biological process that occurs when an organism or cell gains one or more additional sets of chromosomes. It results in a polyploid individual or cell that possesses more than two complete sets of chromosomes. This process can occur naturally through various mechanisms like errors during cell division, crossbreeding between different species, or the fusion of two gametes.
Polyploidisation is frequently observed in plants, but it can also occur in animals, fungi, and certain microorganisms. It can have significant effects on the phenotype and characteristics of the polyploid organism, often leading to enhanced genetic diversity, altered growth patterns, and increased robustness. The process can also lead to the formation of new species or subspecies by generating reproductive isolation mechanisms.
Polyploidisation is of considerable significance in plant breeding and agriculture. Many modern crops, such as wheat, cotton, and potatoes, are polyploids that have been deliberately selected for their desirable traits. Polyploid plants often exhibit increased size, vigor, and resistance to biotic and abiotic stresses. Additionally, polyploidisation plays a crucial role in the evolution and speciation of plants, contributing to their adaptability and survival in changing environments.
In summary, polyploidisation is a biological process in which an organism or cell acquires additional sets of chromosomes, resulting in a polyploid individual. This process can occur naturally or be induced deliberately in certain organisms. It has significant implications for genetic diversity, adaptation, and species formation in plants and other organisms.

Etymology of POLYPLOIDISATION
The word "polyploidisation" is derived from three main components: "poly-", "ploid", and "-isation".
1. "Poly-" is a prefix derived from the Greek word "polus", meaning "many" or "much". It is commonly used in English to denote "multiple" or "many".
2. "Ploid" is a term derived from the Greek word "ploos", meaning "fold" or "folded". In the context of genetics and biology, it refers to the number of sets of chromosomes present in the cells of an organism.
3. "-isation" is a suffix that denotes the action or process of something, often used to form nouns from verbs. In this case, it is added to "polyploid" to form the noun "polyploidisation", representing the process or act of becoming or being polyploid.
