Assertion (A): In a dihybrid cross involving two pure-breeding parents that differ in two traits, the F1 generation shows only the dominant phenotype for each trait.

Reason (R): According to Mendel's law of dominance, in a heterozygous condition, the dominant allele masks the effect of the recessive allele.
