Here the relation between genotype and phenotype is illustrated, using a Punnett square, for the character of petal colour in a pea plant. The letters B and b represent genes for colour and the pictures show the resultant flowers. The genotype is the part (DNA sequence) of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic (phenotype) of that cell/organism/individual.
A phenotype is an observable trait that is the expression of a gene combination, or genotype. Eye color, blood group, and the symptoms of inherited diseases are examples of phenotypes. Chromosomes, and therefore genes, occur in pairs in a diploid organism, such as a human.
