Genetic mapping?

i have been searching the enternet for reference map for the genetic make-up of the human. i have found many but none had what i was looking for. i need not only the location of the genes, but what they do, like which effect skin, hair(including color, texture, and growth), eyes ect. can anyone out there help?


thanks ahead of time.

Genetic mapping?
Genes hold all of our hereditary information, and provide the "genetic code" that allows our bodies to develop, grow, and function. Genes can play a role in our risk to develop certain disorders. Our environment affects how our genes function. Genes are made up of DNA (Deoxyribonucleic Acid.) DNA is the genetic alphabet. We inherit half of our genetic information from our mother, and half from our father. Our genes are packaged in structures called chromosomes. Genes lined up on chromosomes can be thought of like beads lined up on a string. Humans have 23 pairs of chromosomes in almost every cell of their body. These pairs are called homologous chromosomes.





A genetic map is a map based on the frequencies of recombination between markers during crossover of homologous chromosomes. Here is a nice website on the subject http://www.ncbi.nlm.nih.gov/About/primer...
