Question

• A. 1 : 2
• B. 2 : 3
• C. 1 : 1
• D. 2:1

Answer 1

The correct option is D 2:1

Primitive characters- perennial, with many stamens, solitary flowers. Advanced characters- compound leaves, dichlamydeous, zygomorphic, epigynous flowers, multiple fruits, exalbuminous seeds. This gives a total of 6 advanced and 3 primitive characteristics, so the ratio is 6:3, which reduces to 2:1

So, the correct answer is '2:1'
