Question

1. Which characters of organisms are visible

characters?

2. Name the recent approaches in taxonomy.

3. What is DNA barcoding?

4. What is evolution?

5. Enlist uses of taxonomy.
Answer please​

Answer 1

• The physical characteristics of organisms are the visible characters that can be seen from outside. These are known as phenotypic characteristics and are observable as well as a measurable trait. Some of them are colour, size, height, eye colour, body weight, hair colour, etc.
• The major and recent approaches in the field of taxonomy are Morph taxonomy, Cytotaxonomy, Chemotaxonomy, Numerical taxonomy, and Molecular taxonomy.
• DNA barcoding involves the production of PCR amplicons from particular regions to sequence them and these sequence data are used to identify or “barcode” that organism to make a distinction from other species.
• The process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth
• The usage of taxonomy 1) To give the students of biology about the classification of different species. 2) To identify different rare species we use the previously registered taxonomy information. 3) To enlist the newly found species we use the taxonomy classification.

3. DNA barcoding involves the production of PCR amplicons from particular regions to sequence them and these sequence data are used to identify or “barcode” that organism to make a distinction from other specie
4. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection
5. The usage of taxonomy: 1) To give the students of biology about the classification of different species. 2) To identify different rare species we use the previously registered taxonomy information. 3) To enlist the newly found species we use the taxonomy classification
