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.
Answer lies in genetics !! First, a definition - Phenotype is the expression of genotype in a particular environment. Height, size, color, weight and other physical characteristics are result of genes that express themselves. Also they are controlled by more than one gene. But genes do not function alone. The effect of environment + effect of gene gives the final result.
