B) (ii) and (iv)
C) (i), (ii) and (iii)
D) (i), (iii) and (iv)
Correct Answer: B
Solution :
[b] A recessive allele is not weaker than the dominant allele. It (recessive allele) does not show its effect (in the presence of dominant allele) because of modified or different 'enzymes. A recessive allele makes its gene product even when paired with the dominant allele. It is not necessary that dominant allele is always better (in the case of dominant disease).
