Tools that Aid Phylogenetic System Of Classification

Q.

How is cytology useful in taxonomy?

Q. Cytotaxonomy includes the study of:
I. Chromosome number
II. Number of observable characteristics
III. Chromosomal behaviour
IV. Chromosome morphology

1. Only I, II and IV
2. Only I, III and IV
3. Only I and II
4. Only II and III

Q. Chemotaxonomy is based on

1. arrangement of stamen
2. chemical constituents
3. morphology
4. evolutionary relationship

Q.

What is cytotaxonomy?

Q. Classification done on the basis of cytological information, chromosome structure and their behaviour, is known as:

1. Cytotaxonomy
2. Karyotaxonomy
3. Chemotaxonomy
4. Molecular classification

Q. Classification based on features like chromosome number, structure and behaviour is called

1. phylogeny
2. numerical taxonomy
3. cytotaxonomy
4. chemotaxonomy

Q. Classification based on features like chromosome number, structure and behaviour is called

1. phylogeny
2. chemotaxonomy
3. numerical taxonomy
4. cytotaxonomy

Q. Choose the incorrect statement about numerical taxonomy.

1. Cannot be carried out using softwares
2. Hundreds of characters can be considered at a time
3. Each character is given equal weightage
4. It takes into account all observable characteristics

Q. Choose the incorrect pair of chromosome type and the position of centromere in the chromosome:

1. Telocentric: Centromere at one end of the chromosome
2. Metacentric: Centromere at the centre of the chromosome
3. Submetacentric: Centromere nearby the centre of the chromosome
4. Acrocentric: Centromere near one end of the chromosome
