Each cell contains a nucleus (except red blood cells) Our genetic blueprint, inherited from our parents effects all aspects of our development and behavior. Nucleus each contains 46 chromosomes arranged in 23 pairs (1 of each pair. Chromosome contain numerous genes in 2 long twisted strands. Genes segments of dna that have instructions to make protein (the building blocks of life) * effected by genes and by the environment. Dominant genes if the gene received by both parents is dominant. Recessive genes if the gene is recessive, the trait will not be expressed unless the paired gene from the other parent is also recessive. Example: brown eyes and dark hair are dominant over blue eyes and blonde hair. Eye color mother (brown gene) +father (blue gene) child has brown eyes. Mother (blue gene)+ father (blue gene) child has blue eyes. Polygenic effects( ) numerous genes combine to determine a trait.
