Solution

The correct option is C Alleles do not show any blending and both the characters recover as such in F $_{2}$ generation.
Mendel's law of dominance states that recessive alleles will always be masked by dominant alleles. Therefore, a cross between a homozygous dominant and a homozygous recessive will always express the dominant phenotype, while still having a heterozygous genotype. Law of dominance can be explained easily with the help of a monohybrid cross experiment - In a cross between two organisms pure for any pair of contrasting traits, the character that appears in the F1 generation is called 'dominant' and the one which is suppressed is called recessive.
Thus, (D) statement cannot be explained by Mendel's law of dominance.
