AUTOPOLYPLOIDY Meaning and
Definition
-
Autopolyploidy refers to a type of polyploidy that occurs within a species, where additional sets of chromosomes are present in the cells of an individual. Polyploidy occurs when there is an increase in the number of whole sets of chromosomes within an organism's genome. In autopolyploidy, this increase in chromosome sets arises from multiple replication events within the same species, leading to the generation of new cells or individuals with more than two sets of chromosomes.
Autopolyploidy can commonly occur through two main mechanisms: non-disjunction during cell division, where chromosomes fail to separate properly resulting in the formation of diploid gametes that can fuse with other haploid gametes, and endomitosis, where replication of chromosomes within cells does not proceed to cell division.
The presence of extra sets of chromosomes in autopolyploidy can lead to several effects on the individual organisms. It often results in larger cell size, increased vigor, and altered physiological characteristics. Additionally, autopolyploidy can lead to reproductive isolation, reducing the ability to produce viable offspring with individuals from the original diploid population, contributing to speciation.
Autopolyploidy is commonly found in plants and less frequently in animals. It has played a significant role in plant evolution and diversification, contributing to the formation of new species and promoting adaptation to different environments. The study of autopolyploidy aids in understanding genetic diversity, speciation mechanisms, and evolutionary processes within species.

Etymology of AUTOPOLYPLOIDY
The word "autopolyploidy" is derived from Greek roots. Here is the breakdown:
1. "Auto-" is a prefix derived from the Greek word "autós", meaning "self" or "same".
2. "Poly-" is a prefix derived from the Greek word "polýs", meaning "many" or "multiple".
3. "-Ploidy" is a suffix derived from the Greek word "ploîos", meaning "fold" or "multiple".
Therefore, combining these components, "autopolyploidy" refers to a genetic condition characterized by an organism having multiple sets of chromosomes derived from the same ancestral species.
