genotype: A cell's, an individual's, or an organism's genetic makeup (genome). The genotype is separate from the cell's, individual's, or organism's manifested characteristics, or phenotype.
phenotype: is a set of observable characteristics about a person, such as height, eye color, and blood type. The genotype is the genetic contribution to the phenotype. Some characteristics are heavily influenced by genetics, whereas others are heavily influenced by environmental circumstances.:
In endocrinology, tolerance is a biochemical wonder wherein the nearness of one hormone is required all together for another hormone to apply its full consequences for an objective cell.
Hormones can communicate in lenient, synergistic, or hostile ways. glycoproteins,steroids, polypeptides and amines are the chemical classes of hormone.
Permissive hormones are precursor to active hormones and are called as prohormones or prehormones.
You can't always determine an organisms genotype just by looking at them. For example. A dog has black and brown fur, but his skin color could be a whole different color than we can see just by looking at the dog.
