If there are two alleles at a locus, and there is
incomplete dominance - the phenotypic values of AA, Aa and aa are

Broad sense, since (AA) and (Aa) individuals will have
the same phenotypic trait value.
B.
Narrow sense, since (AA) and (Aa) individuals will have
different phenotypic trait values.
C.
Both broad sense heritability and narrow sense
heritability.
