Class 12 NEET Biology Principles of Inheritance and Variation Questions Part 3

Correct option: A, C, D and E only.Mendel's Law of Dominance states that characters are controlled by discrete units called factors.It also states that factors occur in pairs in normal diploid organisms.In a dissimilar pair of factors, one factor is dominant and the other is recessive.Therefore, statements A, C and D are explained by the Law of Dominance.The Law of Dominance also explains that in a monohybrid cross only one parental character is expressed in the $F_1$ generation.Thus, statement E is also explained by the Law of Dominance.Statement B relates to the Law of Segregation, not the Law of Dominance; in its standard form, alleles do not show blending and both parental characters reappear as such in the $F_2$ generation.Hence, B is excluded.So the correct combination is A, C, D and E only.
