How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

• There is no difference

• The heterozygous genotype has a unique phenotype

• There is no heterozygous genotype

• There is only one phenotype regardless of genotype.

A ​ (a)   is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by ​ (b)   . For example, BB, Bb, bb could be used to represent a given variant in a gene.
