ABO-Rh Blood Typing With Synthetic Blood. Hair texture Table 12-3 p. 109 #8: CC, SC(wavy), SS.

• Blood groups: antigen on RBC: O produce anti-A, anti-B, can agglutinate (clump).
  Rh+ baby (inherit from father) RBC can cross placenta at birth (placental rupture) to Rh- mother, may produce antibody, can cross to agglutinate in subsequent Rh+ fetus - anemia and jaundice. O Negative is universal donor.
• Curly hair (CC) is incompletely dominant to straight hair (SS). CS wavy hair.
• Thalassemia recessive: missing Hb chain; sickle-cell abnormal Hb. Hemoglobin alpha & beta chains.
