The genotype and phenotype of a living organism are linked to one another by a simple relationship. The phenotype of even the simplest organism on earth is very, very complex. These complex phenotypes can be analyzed by breaking them down into smaller, discrete sections or components called traits . Assume that this plant has red flowers. A plant's flower is part of its reproductive system.
Flowers are the sex organs of certain plants and hold the male and female gamete producing systems.
Flowers are also where fertilization takes place. Most wavelengths of the light are absorbed and only the red light is reflected. Pigment is produced in the petal cells of the plant as the result of a chemical reaction. The key role of proteins Proteins play key roles within all cells. The genotype of a cell contains the biological information needed to join amino acids together in the correct sequence to produce an active protein.
