Document Summary

Genetic endowment combines with environmental forces to determine our behaviour. Psychologists working in the field of behaviour genetics study which favourable or unfavourable environmental conditions can affect the genetically inherited potential of an organism. Genotype specific genetic make-up of an individual. Phenotype observable characteristics produced by that genetic endowment. Genotypes are present from conception and never change. Phenotypes can be affected by other genes and by the environment. Union of two cells (egg from the mother and sperm from the father) is the beginning of a new individual. The egg and sperm carry within them the material of heredity in the form of rodlike units called chromosomes. Chromosome tightly coiled molecule of dna that is partly covered by protein. Dna portion of the chromosome carries the hereditary blueprint in units called genes. Every cell in the human body except one type (sex cell) has 46 chromosomes.
