Question

Match the genetic phenomena with their respective ratios

a	Inhibitory gene ratio	1	9 : 3 : 4
b	Complementary gene ratio	2	1 : 1 : 1 : 1
c	Recessive epistasis ratio	3	12 : 3 : 1
d	Dihybrid test cross ratio	4	13 : 3
e	Dominant epistasis ratio	5	9 : 7

• A. a-5, b-4, c-3, d-2, e-1
• B. a-4, b-5, c-1, d-2, e-3
• C. a-1, b-2, c-4, d-3, e-5
• D. a-2, b-1, c-4, d-5, e-3
• E. a-5, b-4, c-1, d-2, e-3

Answer 1

The correct option is A a-5, b-4, c-3, d-2, e-1

A.Inhibitory gene ratio – 9:7

B.Complementary gene ratio – 13:3

C.Recessive epistasis ration – 12:3:

D.Dihybrid test cross ratio – 1:1:1:1

E.Dominant epistasis ratio – 9:3:4

So, the correct option is ‘a-5, b-4, c-3, d-2, e-1’.
