Document Summary
Our genetics combined with environmental factors determine our behaviour. Takes into account both nature and nurture. Hippocrates was the first to suggest that semen contains some sort of design for the formation of the offspring| Mendel confirmed this year later, showing that heredity involves the passing on of specific organic factors not the blending of parents characteristics. Genotype: the specific genetic makeup of the individual. Phenotype: the observable characteristics produced by the genetic makeup| Can be affected by other genes & by the environment. Chromosome: a tightly coiled molecule of dna that is partly covered by protein. The egg & sperm carry hereditary materials in the form of chromosomes. Genes: the dna portion of the chromosome carries hereditary blueprint in units called genes. Every cell in human body (except one type) has 46 chromosomes. Sex cells (egg or sperm) only have 23 then they combine @ conception. Dominant: the particular characteristic that a gene controls will be displayed.
