NEET Biology question
Match the genetic phenomena with their respective ratios.
| Column-I | Column-II | |---|---| | (A) Inhibitory gene ratio | (1) | | (B) Complementary gene ratio | (2) | | (C) Recessive epistasis ratio | (3) | | (D) Dihybrid test cross ratio | (4) | | (E) Dominant epistasis ratio | (5) |
Answer: (A)
Solution
An inhibitory gene interaction modifies the dihybrid ratio to (A-4); complementary gene interaction gives (B-5), since both dominant genes must be present together for the trait to show;
