Question

Which of the following fill not be the nature of enzyme encoded by a recessive gene?

(a) Less efficient enzyme

(b) No function observed for the enzyme

(c) Abnormal function of the enzyme

(d) More efficient enzyme

I have been asked this question in exam.

This key question is from Inheritance Principles topic in section Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Correct answer is (d) More efficient enzyme

To elaborate: Recessive alleles lose the capability to encode because of the presence of a better functioning allele. Hence a more efficient enzyme is highly unlikely to be encoded by a recessive gene.
