Genes are the term for groups of genetic code, as DNA, that define inherited traits. Genes control all of your physical traits, such as height, eye color, hair color, predisposition for diseases such as Diabetes, and, it is believed, predispositions for behavior as well. They are literally the coding for who you are, both physically, and in some part personality wise. however, your personality is also greatly affected by environment.
In a nutshell: genes are the instructions to your cells for your physical traits and the predisposition to certain personality traits.

what can somtimes influence expression of genes
The Human Genome Project's purpose is to analyze and map the entire human genome -- that is, to determine all the genes that are involved in human biology. They're doing this to correlate genes to the traits they influence so that the genes (or lack thereof) responsible for disease can be identified.
They include environment, races, heredity, learning, sex and nutrition. Growth and development is the process of a human being advancing from childhood to maturity.
The blood type in humans
The environment.
The human genome contains about 24,000 genes.
Genes that segregate independently do not influence each other's inheritance because they are located on different chromosomes. However, the expression of genes that segregate independently can still influence one another.
The human genome project began in 1990, and this project was to find the complete sequence of genes in a human. The goal of this project was to identify all genes in the human body, this meant as much as mapping out 3 billion base pairs of nucleotides in our DNA. It was completed in 2003 and this now allows for further development in biological diseases and also gives us a thorough analysis in human Biology.

Hox genes are a group of related genes that are specific for the anterior and posterior axis of an organism in embryonic development. They assist in the formation of segments in the developing animal.
