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.
Alleles whose expression is masked by dominant alleles are recessive, and are designated by a lower case letter (for example, b). The genotype of an organism includes all the alleles present in the cell, whether they are dominant or recessive. The Biochemical manifestation of the trait is called the phenotype.
