Rh Group

Weiner vs Fisher-Race Nomenclature

Weiner

Genetic Theory:

  • 1 gene, 3 "factors"

D antigen present

  1. Ro

  2. R1

  3. R2

  4. Rz

D antigen absent

    5. r

    6. r'

    7. r"

    8. rY

Fisher- Race

Genetic Theory: 

  • 3 genes

    • D, Cc, Ee​

D antigen present:

  1. Dce

  2. DCe

  3. DcE

  4. DCE

D antigen absent

    5. ce

    6. Ce

    7. cE

    8. CE

So a person with an R1r" Wiener nomenclature would have DCe/cE Fisher-Race nomenclature when converted.

  • It is important to be able to convert from Weiner to Fisher-Race and vice versa
