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.n the case of an albino with a recessive allele (aa), the phenotype depends upon the other allele (Aa, aa or AA). An affected person mating with a heterozygous individual (Aa or aA, also carrier) there is a 50-50 chance the offspring will be albino's phenotype.
