Answer
The three possible genotypes of a pair of alleles for monogenic traits are homozygous dominant, heterozygous, and homozygous recessive.
Most human traits are polygenic and many are associated with codominance. Of the normal monogenic traits two examples are are dimpled cheeks and cleft chin.
If we assign "D" to represent the allele fo cheek dimples and the letter "d" to represent the recessive allele (absence of cheek dimples), the three genotype are possible are:
D/D-- homozygous dominant; D/d--heterozygous , and d/d , homozygous (double) recessive.
