Document Summary

Psychology lecture 5- chapter 4: genes, evolution, behaviour. Our genetic blueprint, inherited from out parents effects all aspects of our development and behaviour. Cells- 100 trillion in the body (all cells contain nucleus expect red blood cells) Nucleus- each contains 46 chromosomes arranged in 23 pairs. Chromosome- contain numerous genes in long twisted strands. Genes- segments of dna that have instructions to make protein (the building blocks of life) Dominant genes- if the gene received by both parents is dominant, the trait will be expressed. Recessive genes- if the gene is recessive, the trait will not be expressed unless the paired gene from the other parent is also recessive. Ex. brown eyes and dark hair are dominant over blue eyes and light hair. Polygenic effects- numerous genes contribute to determine a trait. Genetic counseling- identify whether a person has the specific genes that will result in certain diseases. Huntington"s disease, breast cancer (provide medical counseling and support)
