The spelling of the word "thelytoky" is based on the International Phonetic Alphabet (IPA) which is a standardized system of phonetic notation used to represent the sounds of spoken language. The word is pronounced as "thuh-lee-tuh-kee" (θiːliːtɒki) and refers to a reproductive strategy in which females produce offspring without fertilization. Even though the word may seem complex, understanding its phonetic transcription can help in correctly pronouncing and comprehending its meaning.
Thelytoky is a biological phenomenon that refers to a form of reproduction in which females produce offspring without the involvement of males or the need for fertilization. Derived from the Greek words "thēlē" meaning female, and "tokos" meaning birth, the term thelytoky can be commonly observed in certain animal species, primarily insects and plants.
In certain ants, bees, and wasps, thelytoky occurs when unfertilized eggs develop into females. The resulting offspring are typically clones of their mothers, carrying identical genetic information. This form of reproduction is seen as an adaptation that allows these species to efficiently propagate, particularly in situations where males are scarce or unnecessary for successful reproduction.
In plants, thelytoky occurs through various mechanisms such as the development of adventitious embryos or the production of seeds without pollination. This allows plants to reproduce asexually, bypassing the need for genetic recombination through sexual reproduction. Many agricultural crops and horticultural species exhibit thelytoky as a means of efficient multiplication and propagation.
Thelytoky is a fascinating aspect of reproductive biology that challenges the traditional understanding of sexual reproduction. Its occurrence in different organisms demonstrates the variety of reproductive strategies in the natural world and the remarkable adaptability exhibited by various species.

The word "thelytoky" originates from the combination of two Greek words: "thēlys" meaning "female" or "woman", and "tokos" meaning "birth" or "offspring".
