Final answer:

In a diploid organism, b) co-dominance of alleles does not involve one gene masking the activity of another gene.

Step-by-step explanation:

In a diploid organism, the following statement is false:

b. Co-dominance of alleles involves one gene masking the activity of another gene.

Co-dominance is a form of inheritance in which both alleles for a trait are expressed equally in the heterozygous individual.

In co-dominance, neither allele masks the activity of the other.

An example of co-dominance is the MN blood groups in humans, where both M and N alleles are expressed equally.
