Give scientific reasons on:Phenotypic and genotypic ratios are different.
Answer»
Phenotype means external appearance or visible characteristics of organisms whereas the genotype is the pairs of genes responsible for the visible characteristics.
The genes responsible for any particular character are present in pairs.
Though, there are two genes, the phenotype depends on the presence of the dominant gene, e.g. Genotype for tall height of the plant is TT or Tt.
Therefore, phenotypic and genotypic ratios are different.
