Dear Student

Please find below the solution to the asked query

Co-dominance is the condition in which both the alleles of a
particular trait are expressed in a heterozygous condition and both
are equally dominant ABO blood group shows co-dominance because the
alleles, IA and IB, are equally dominant when they are expressed in
AB blood group Both these alleles do not interfere with the
expression of each other and produce their respective
antigens

Allele from Parent 1

Allele from Parent 2
