How Do You Spell MULTIGENE?

Pronunciation: [mˌʌltɪd͡ʒˈiːn] (IPA)

The word "multigene" refers to the presence of multiple genes in an organism. The spelling of this word is determined by its phonetic transcription. In IPA (International Phonetic Alphabet) notation, "multi" is transcribed as /ˈmʌlti/, indicating the pronunciation of the word "mull-tee". "Gene" is transcribed as /dʒiːn/, pronounced as "jean". Combining both transcriptions together, "multigene" is pronounced as /ˈmʌltiˌdʒiːn/, sounding like "mull-tee-jean". This spelling accurately reflects the pronunciation of the word and helps in its correct usage in scientific discourse.

MULTIGENE Meaning and Definition

1. Multigene is an adjective that refers to the involvement or presence of multiple genes in a particular characteristic or process. It describes a complex situation where the expression, regulation, or inheritance of a trait is determined by the combined action of more than one gene.

   In genetics, traits that exhibit multigene inheritance do not follow the straightforward Mendelian patterns of inheritance observed in traits controlled by a single gene. Instead, they arise from the interaction of multiple genetic factors, often accompanied by environmental influences. This interplay makes the understanding and prediction of these traits more intricate.

   The term multigene can also be used to describe gene families that consist of multiple related genes with similar DNA sequences and functions. These gene families can evolve over time through duplication and divergence, resulting in diverse biological functions performed by different members within the family.

   Further, the concept of multigene can extend to larger systems, such as multigene networks or pathways, where multiple genes cooperatively interact to regulate a particular biological process. These networks can involve various genes with distinct functions that work together to achieve a specific outcome.

   In summary, multigene refers to the involvement of multiple genes in the determination of a trait, the presence of gene families with similar sequences and functions, or the interaction of multiple genes in complex biological processes or networks.

Etymology of MULTIGENE

The word "multigene" is formed by combining the prefix "multi-", derived from the Latin word "multus" meaning "many" or "multiple", and the word "gene", which comes from the Latin "genus" meaning "race" or "kind".

The term "gene" was first used in 1905 by the Danish botanist Wilhelm Johannsen to describe the units of heredity responsible for the transmission of traits from parents to offspring. The concept of a single gene being responsible for a single trait was prevalent at the time, but it later became recognized that many traits are actually influenced by multiple genes.

As a result, the prefix "multi-" was added to "gene" to create the word "multigene", indicating a situation where multiple genes are involved in the expression or determination of a particular trait.
