ABO

Protein sy'n cael ei godio yn y corff dynol gan y genyn ABO yw ABO a elwir hefyd yn alpha 1-3-N-acetylgalactosaminyltransferase (Saesneg). Segment o DNA yw'r genyn, sy'n amgodio ffwythiant arbennig. Mae'r genyn yma wedi ei leoli ar yr edefyn ôl o gromosom dynol 9, band 9q34.2.

Cyfystyron

Yn aml mae gan enynnau lawer o gyfystyron. Mae hyn oherwydd eu bod yn aml yn cael eu darganfod gan nifer o bobl mewn cyd-destunau gwahanol heb wybod mai'r un genynnau oeddyn nhw. Hefyd mae gan wahanol gymunedau gwyddonol safonau gwahanol ar gyfer enwi genynnau. Dyma restr o gyfystyron ar gyfer y genyn ABO.

• GTB
• NAGAT
• A3GALNT
• A3GALT1
