As was done later by MARRYAT (1909), KIERNAN & WHITE (1926) and SHOWALTER (1934) he showed that a dominant allele Y conditions the production of yellow pigment or pigments, whereas the dominant allele R effects red pigment or.

The stem has not yet fallen off, but will so as the plant forms a suberised abscission layer at any stem node, including the root neck. Plants grown by Judy Glattstein. Option (2) Flower colour in snapdragon - also shows incomplete dominance, just like Mirabilis jalapa.
Option (3) Fur colour in rabbit - influenced by multiple alleles. Option (4) Skin colour in humans - is a polygenic trait. Step 3: Conclusion.
Since both Mirabilis jalapa and snapdragon exhibit incomplete dominance, option (2) is correct. The color phenotype and pigment contents of the corolla of M. jalapa with different flower colors during flowering were which were tested by chromometer and ultraviolet.
