4.Principles of Inheritance and Variation
normal
A recessive gene is one which
A
Occurs less frequently than a dominant one
B
Occurs only in heterozygotes
C
Produces large amounts of $RNA$
D
Produces very less or no $mRNA$
Solution
(d) A recessive gene is one which is not able to synthesize a functional polypeptide and hence it is not expressed phenotypically,
therefore that part of $DNA$ does not transcribe $mRNA$ or very little of $mRNA.$
