Co – Dominance: When two alleles of a gene are equally dominant and express themselves when they are together.
Example blood group AB
Dominant Allele IA produces glycoprotein A
Dominant Allele IB produces glycoprotein B
When IA and IB remain together they produce both glycoprotein A and B as in case of blood group AB (Genotype IA IB )
Co Dominance and multiple allelisim
Crosses of blood group (CO DOMINANCE)
