प्रश्न
Explain the law of dominance in a monohybrid cross.
उत्तर
Law of dominance states that the offsprings of an individual with contrasting (dissimilar) traits will only express the dominant trait in the F1 generation and both the characters are expressed in the F2 generation. This law also explains the proportion of the 3: 1 ratio in the F2 generation.
