  1. BLOOD TYPES

  2. TYPES • TYPE A • TYPE B • TYPE AB • TYPE O

  3. CODOMINANCE • 2 Dominant alleles are expressed at the same time • Controlled by multiple alleles • The A gene and the B gene are dominant which is why you can have Type AB blood

  4. USES • Use blood types to determine paternity & crime scene investigation (blood spatter, comparing blood types to suspects & victims) • Now they use DNA because it is more reliable

  5. Type O- universal donor • Type AB- universal recipient • Type O- can only receive Type O blood • Type A- can get Type A or O • Type B- can get Type B or O • Type AB- can get all four

  6. POSSIBLE ALLELES • A- DOMINANT • B- DOMINANT • O- RECESSIVE TYPE ATYPE BTYPE ABTYPE O AA BB AB OO AO BO
