Codominance.
Codominance occurs when, for example, a Dominant Blue color gene for a leaf crosses with a Dominant White color gene for a leaf. The genotype would be BW. This would result in, for example, a blue and white spotted leaf color. INCOMPLETE dominance occurs when both dominant alleles blend together, resulting in, eg, a pale blue color resulting from the blue and white colors mixing.
The circulatory system is the form of transport in plants and animals. Animals should have nutrients and oxygen that spread every cell in their body. Plants should have nutrients and carbon dioxide spread in their "body". Both plants and animals must also have waste product away from their systems.
