The F₂ ratio in polymeric gene action is

A. 9 : 3 : 4

B. 12 : 3 : 1

C. 9 : 4 : 2

D. 9 : 6 : 1

Answer: Option D

Solution(By Examveda Team)

The F2 ratio in polymeric gene action is 9 : 6 : 1.
Polymeric gene carriers are a potential alternative to using viral vectors. Polymeric carriers have relatively low immunogenicity and cytotoxicity.
In addition, polymeric carriers can accommodate large-size DNA, be conjugated with appropriate functionalities, and be administered repeatedly. The F₂ ratio in polymeric gene action is 9 : 6 : 1.
