Autotriploid is a term that is often used in the field of genetics and biology. It refers to a type of organism that has three sets of chromosomes, all of which come from the same species. In this article, we will explore the definition, origin, meaning, associations, synonyms, antonyms, root words, and example sentences related to autotriploid.
Definitions
The term autotriploid is derived from the Greek words “auto” meaning “self,” “tri” meaning “three,” and “ploid” meaning “fold.” Therefore, autotriploid refers to an organism that has three sets of chromosomes, all of which come from the same species.
In simpler terms, autotriploid is a type of polyploid that has three copies of each chromosome in its cells. It is a rare occurrence in nature, but it can be induced in plants through various methods such as chemical treatments, irradiation, or cross-breeding.
Origin
The origin of autotriploid can be traced back to the process of polyploidization, which is the duplication of the entire set of chromosomes in an organism. This process can occur naturally or artificially and can result in organisms with different ploidy levels, including autotriploid.
In nature, autotriploid organisms are rare, but they can be found in certain species of plants, such as strawberries, bananas, and apples. In agriculture, autotriploid plants are often cultivated for their desirable traits, such as larger fruits or higher yields.
Meaning in different dictionaries
The meaning of autotriploid in different dictionaries is consistent with the definition outlined above. For example, the Merriam-Webster dictionary defines autotriploid as “having three sets of homologous chromosomes derived from a single species.”
Similarly, the Oxford English Dictionary defines autotriploid as “a cell or organism containing three sets of chromosomes, all derived from the same species.”
Associations
Autotriploid is often associated with genetic diversity, as it can result in new combinations of genetic material that may lead to novel traits or characteristics. It is also associated with polyploidization, which is a common mechanism of evolution in plants.
In agriculture, autotriploid plants are often associated with higher yields, larger fruits, and improved resistance to disease and environmental stress.
Synonyms
Some synonyms of autotriploid include triploid, 3n, and AAA.
Antonyms
The antonyms of autotriploid are diploid, which refers to an organism with two sets of chromosomes, and tetraploid, which refers to an organism with four sets of chromosomes.
The same root words
Autotriploid shares its root words with other terms related to ploidy levels, such as monoploid, diploid, tetraploid, and hexaploid.
Example Sentences
Here are some example sentences that illustrate the use of autotriploid:
- The strawberry cultivar we grow is an autotriploid, which means it has three sets of chromosomes from the same species.
- Autotriploid plants are often more robust and resistant to disease than their diploid counterparts.
- The production of autotriploid bananas has led to larger and more flavorful fruits.
- Polyploidization can result in autotriploid organisms, which can have unique traits and characteristics.
- The autotriploid apple cultivar we planted has a much higher yield than our previous diploid cultivar.
