Allogamous is a term that is commonly used in the field of biology to describe the process of fertilization that occurs between two different individuals of the same species. In this article, we will explore the definition and meaning of allogamous, as well as its origins, associations, synonyms, antonyms, and example sentences.
Definitions
The term allogamous can be defined as the process of fertilization that occurs when the gametes (reproductive cells) of two different individuals of the same species combine to form a zygote (a fertilized egg). This is in contrast to autogamous fertilization, which occurs when the gametes of the same individual combine to form a zygote.
Origin
The term allogamous is derived from the Greek words “allo” (meaning “other”) and “gamus” (meaning “marriage”). It was first used in the late 19th century to describe the process of fertilization between two different individuals of the same species.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, allogamous is defined as “characterized by cross-fertilization between individuals of the same species”. The Oxford English Dictionary defines it as “characterized by the fusion of gametes from different individuals of the same species”.
Associations
Allogamous fertilization is a common process in many different types of plants and animals. It is often associated with increased genetic diversity and the ability of a species to adapt to changing environments.
Synonyms
Some synonyms for allogamous include cross-fertilization, outbreeding, and hybridization.
Antonyms
The antonym of allogamous is autogamous, which refers to the process of self-fertilization.
The same root words
The root words of allogamous are “allo” and “gamus”. These words are also found in other biological terms, such as allopatric (referring to the geographic separation of populations of the same species) and gamete (referring to the reproductive cells that combine during fertilization).
Example Sentences
- “The allogamous fertilization of these plants allows for greater genetic diversity and adaptability.”
- “Autogamous plants are often less genetically diverse than allogamous ones.”
- “The process of allogamous fertilization can result in the creation of new hybrid species.”
