Document Summary

Psychology chapter 4 - genes, evolution and behaviour. Genotype is the specific genetic makeup of an individual, present from conception and remain constant. Phenotype is the observable characteristics caused by a genotype, can be affected by other genes and the environment. Proteins control structure of cells, and chemical reactions within bodily cells. Each individual gene codes for specific protein, and activated genes will cause body to produce specific protein.

Each chromosome has genes (hereditary blueprints) that code for certain trait, and alleles that produce different characteristics. Has 46 chromosomes, except sex cell, which has 23. Has a nucleus that contains genetic code for entire body. Has two copies of each gene, one from each parent.
