What is a gene?

A gene is a specific fragment of the DNA molecule, which is used as a template to create a protein by successive processes of transcription and translation.

  • The variants or forms of a gene are called alleles, diploid individuals receive two alleles (one for the mother and another from the father).

  • An individual is homo-zygous when he/she has the same alleles for a given gene locus, while an individual is heterozygous when he/she has different alleles for a gene locus.

In conclusion, a gene is a segment of DNA that is the basic unit of heredity.
