Question

Explain about phenetic classification​

Answer 1

In this, Organisms with most of the similarities are placed in a particular group of their kind.

• All the characters are given equal importance and so hundreds of characters can be considered.
• So in this classification importance is not given to any particular character instead all characters are considered equally important.

Answer 2

Explanation:

Phenetic Classification​:

• Phenetic classification is a type of numerical taxonomy.
• In this type of classification the organisms are  arranged  according  to  overall  similarity  of  existing organisms based on available characters.
• It is also called Adansonian taxonomy because the same was first attempted by Adanson (1763), of course on the basis of external traits only.
• Numerical taxonomy evolved around 1950. It has received impetus with the availability of calculating machines and computers.
• In numerical taxonomy as many characters as possible are employed for evaluating degree of similarity and difference.
• All characteristics used in analysis are given equal weightage and  importance.  
• A  proper  selection  of  characters,  their organization and analysis in the light of current knowledge is  key to  success  of  this  method.
• A lot  of  subjectivity can creep in depending upon the judgement of the biosystematist.
• No weightage is given to the quantity of the character present
