Document Summary

Psycho 104, lecture 9: genes, evolution & behavior. 06/02/19: every cell in your body (apart from sperm cells and egg cells) has46 chromosomes, they are parcelled up into 23 pairs of chromosomes, cells have a nuclei which have chromosomes which have genes. If both your parents are nearsighted since the gene is recessive you would be nearsighted: ex. Take a bacterial cell, open up the dna, extract and insert human gene (e. g. , growth hormone). Reinsert the combined dna back into the bacterial cell: knockout procedures usually involve altering specific genes so they stop functioning properly. Behaviour can be observed before and after ko: destruction of certain genetic information, but cause and effect may be difficult to show since change in one gene might impact operation of others. Identical twins: same zygote splits in half, monozygotic, 100% genetic material, approximately 1/3. Fraternal twins: separate zygotes, dizygotic, 50% genetic material.
