Co-dominance and Multiple Alleles

Co-dominance is shown by 2 alleles that are neither dominant or recessive. In the heterozygous condition, they produce a phenotype that is different from the homozygous state of either allele.

As neither allele is dominent, the different alleles are represented by a different upper case letter for each allele. e.g. R (for ared flower) W (for a…

Hey, I'm doing A2 human biology. I kind of understand the concept of co-dominance, meaning that too dominant allele are expressed through the phenotype. However, I do not understand the second sentence of your explanation, I have a similar sentence in by HBIO booklet which I do not understand either...

"In the heterozygous condition, they produce a phenotype that is different from the homozygous state of either allele."

Could you please help me out and help me understand what it means???

Thank you,

Jessie :)
