View submission: What makes one feature dominant and other recessive?

Here is another insight, consider this picture[1] , this is an example of the phenomenon of incomplete dominance. In incomplete dominance whenever a locus contains 2 types of alleles that are heterozygous i.e. nonsimilar (Rr) the flower color results in pink in color but when all the dominant alleles (RR) are present at that locus the flower color results in deep red, similarly when recessive alleles are present the flower color results to white. This happens due to the different combinations of dominant and recessive alleles when they are present at the same locus.

One other example is Complementary genes picture[2] when a dihybrid locus contains two dominant genes (CcPp, CCpP, CCPP, CcPP) then only certain flower color would be expressed or another phenomenon, but when the two dominant genes aren't expressed together(Ccpp, CCpp, ccPP, ccPp, ccpp) then that flower colur would be changed onto some different color.
