A gene is a section of DNA located at a particular site on a DNA molecule, called its locus. The base sequence of each gene carries the coded genetic information that determines the sequence of amino acids during protein synthesis. Gene expression, also called protein expression or often simply expression is the process by which a gene 's DNA sequence is converted into the structures and functions of a cell. Gene expression is a multi-step process that begins with transcription of DNA, which genes are made of, into messenger RNA.

Different forms of a gene (e.g., normal and mutant) are referred to as alleles. Since diploid organisms carry two copies of each gene, they may carry identical alleles, that is, be homozygous for a gene, or carry different alleles, that is, be heterozygous for a gene. Genetics arose out of the identification of genes, the fundamental units responsible for heredity. Genetics may be defined as the study of gene s at all levels, including the ways in which they act in the cell and the ways in which they are transmitted from parents to offspring. genetics definition: 1. the study of how, in all living things, the characteristics and qualities of parents are given….

Since diploid organisms carry two copies of each gene, they may carry identical alleles, that is, be homozygous for a gene, or carry different alleles, that is, be heterozygous for a gene.

The gene alleles is known as the phenotype, and the physical traits that these genes produce is known as the phenotype. Other Gene Interactions Not all genes have the alleles follow dominant/recessive relationship. Genes can also be controlled by incomplete dominance, co-dominance, and polygenic traits.
