The physical expression of genes are phenotype. Phenotype is the expression of the gene by the appearnace of the organism. It is the characteristics of that trait.
Examples : When pigment is made in our eyes, height ( tall and short) , weight, blond hair is the phenotype for the blond hair genotype and skin colour( black, white ) is the phenotype trait.
Well, when a plant or animal dies in a damp environment it will most likely get buried in mud or silt. The tissues over time will decompose and leave bones or shells behind ( depending on what was there originally it can vary) Eventually over time sediment builds up and hardens into rock.

Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit. These pair up to make a total of 46 chromosomes.
