4 blood types

A,B,o Blood Typing Genes “A” and “B” are co-dominant genes Gene “o” is the recessive gene.

Blood Type: Mom is hybrid type B blood, Dad is hybrid type A blood. 1. Dom = A & B Rec= O 2. A and B and o 3. Mom= Bo Dad= Ao 4. ooAB 5/6. 7. Genotypes = 25% Bo AB Ao oo Phenotypes = 25% Types AB, B, A, and O Ao BABBo oAooo

Rh Factor Blood Type Rh+ means that have protein Rh- means that lack protien The dominant gene is + The recessive gene is -

Rh Factor Dad is heterozygous Rh + factor and mom is homozygous for Rh - factor blood. 1. Dom = Rh + Rec= Rh = Rh+ - = Rh- 3. Mom = -- Dad = /6. 7. Genotypes = 50% Phenotypes = 50% Types Rh + and Rh
