Short definition of gene
SpletMeaning of Gene Interactions: When expression of one gene depends on the presence or absence of another gene in an individual, it is known as gene interaction. The interaction of genes at different loci that affect the same character is called epistasis. The term epistasis was first used by Bateson in 1909 to describe two different genes which ... SpletThe concept of gene (but not the word) was first set forth in 1865 by Gregor Johann Mendel. Until then, little progress has been made in understanding heredity. For many reasons, the result of Mendel’s experiments went unappreciated until the turn of the last century, well after his death. Once Mendel’s publications were rediscovered by ...

SpletWhat is an allele? Well, alleles are matching genes; one from our biological mother, one from our biological father.

Spletgene is “the image of the gene product in DNA”, no matter how the image is broken or distributed and how many regulations are implicated in determining the sequence of proteins. This definition is interesting, but it is only a part of a more global and pluralistic understanding of the gene in the postgeno-mic era.
