Genetics (in psychology): the processes involved in turning genes on and off . Within every cell in the body is the genome, genetic makeup, for making the entire organism. Each cell has a certain option (what they do) but this depends on the environment because the environment determines which options are taken (what genes are turned on and off in a cell). Within each cell are chromosomes, structures made of genes. Typical human has 23 pairs of chromosomes, half of each pair coming from each parent. Genes are components of dna, and the sequence of the genes produces a certain protein which carries out a specific task. The environment determines what protein is produced and when.
