If both parents have the genotype Aa Bb Cc Dd, their phenotype is determined by the dominant alleles for these four traits. If we observe on trait, we have 3 times bigger possibility for a dominant (AA, Aa, and Aa) than recessive phenotype (aa). Since we observe four different traits, the probability for an ofFSPring to look like their parents is   The number of possible phenotypes is 2 for each of the 4 traits (for example Aa and aa for the first trait), which makes it 16 (2 2 2 * 2).
