Document Summary

Module 3. 1 genetic and evolutionary perspectives on behaviour. Genes the basic units of hereditary; genes are responsible for guising the process of creating the proteins that make up our physical structures ad regulate development and physiological processes throughout the lifespan. Dna (deoxyribonucleic acid) a molecule formed in a double-helix shape that contains four nucleotides: adenine, cytosine, guanine and thymine. Genotype the genetic makeup of an organism the unique set of genes that comprise that individual"s genetic code. Phenotype the physical traits or behavioral characteristics that show genetic variation, such as eye colour, she shape and size of facial features, and even personality. Chromosome structures in the cellular nucleus that are lined with all of the genes an individual inherits. Trisomy an extra chromosome is present thus altering the genetic make-up as well as the phenotype is the individual. Homozygous if two corresponding genes at a given location on a pair of chromosomes are the same.
