Why are reproductive characters given more weightage during advanced classification?

(1) Vegetative characters are more or less constant over the generation

(2) Reproductive characters are less constant over the generation

(3) Vegetative characters are easy to get affected by environment

(4) Reproductive characters are more or less constant over the generation

(1) Artificial system

(2) Natural system

(3) Phlogenetics

(4) Numerical system

(1) External features

(2) Phylogeny

(3) Anatomy, Embryology

(4) Phytochemistry

(1) Evolutionary relationships between the various organism

(2) Organisms belonging to the same taxa may have a different ancestor

(3) Both A and B

(4) Based on cytological information like chromosome number, structure, behavior.

(1) Artificial classification

(2) Natural classification

(3) Cytotaxonomy

(4) Phylogenetic classification

(1) Carried out using computers

(2) Based on all observable characteristics

(3) Number and codes are assigned to all the characters

(4) All of these

(1) Based on cytological information like chromosome number

(2) Based on cytological information like chromosome structure

(3) Based on cytological information like chromosome behavior

(4) All of these

(1) Chemical constituents of the plant

(2) Cell structure

(3) Phylogeny

(4) Embryology
