Biology Principles of Inheritance and Variation MHT CET

Match the genetic phenomena with their respective ratios. Column I | Column II A. Inhibitory gene ratio | 1. 9:3:4 B. Complementary gene ratio | 2. 1:1:1:1 C. Recessive test cross 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 – 3Correct
(C)A - 1, B - 2, C - 4, D - 3, E – 1
(D)A - 2, B - 1, C - 4, D - 5, E – 3

Answer: (B)

Solution

Inhibitory gene gives 13:3 (A-4), complementary genes give 9:7 (B-5), the recessive epistasis ratio is 9:3:4 (C-1), a dihybrid
