Q. A perennial shrub has compound leaves and solitary zygomorphic and epigynous flowers. Each flower reveals dichlamydeous condition with many stamens and multiple fruit with exalbuminous seeds. What is the ratio of advanced and primitive characters in it?
A) 1:2
B) 2:3
C) 1:1
D) 3:2
Explanation
According to phylogenetic system of classification, primitive charecters are perenniall and shrubby nature, solitary flower, numerous stamens multiple or aggregate fruit, while advanced characters are compound leaves, zygomorphic flowers, epigynous flowers, fused stamens (dichlamydeous condition) and albuminous seeds. Thus, the ratio of advanced and primitive characters according to question is 1:1.
