One of about 20,000, to 25,000 sections of DNA contained in our cell nuclei, that determine phenotype, or any characteristic, from hair color, eye color to proteins or sugars expressed on our red blood cells giving it the blood "type".
The site I reference is about the human genome project and is fascinating, I suggest you browse through it, will give you a good idea of what is going on in that field.

A gene is the unit of heredity in living organisms. Genes are encoded in an organism's genome, composed of DNA or RNA, and direct the physical development and behavior of the organism. Most genes encode proteins, which are biological macromolecules comprising linear chains of amino acids that effect most of the chemical reactions carried out by the cell.
Some genes do not encode proteins, but produce non-coding RNA molecules that play key roles in protein biosynthesis and gene regulation. Molecules that result from gene expression, whether RNA or protein, are collectively known as gene products.

It is in your nucleus.
Gene is what controlled and shaped you since you were the size of a cell.
Did you hear about genetic make-up? It is your genes that shaped you how you are now: physically, mentally, socially, and god knows what else.
You possess many different genes. Genes are made up of specific sequences of DNA. There are many genes in a chromosome, and 23 pairs of chromosomes make up a human cell's nucleus.

Main Entry: gene
Pronunciation: 'jEn
Function: noun
Etymology: German Gen, short for Pangen, from pan- + -gen
: a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of other genetic material

a gene is a section of a strand of DNA that determines a physical feature about yourself such eye color, etc.
