Question

Why can’t morphological features be used to study variation? What is the exception? Discuss this exception in detail.

Answer 1

Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features.

Morphological texonomy is the first requirement. Without classical taxonomy it is impossible to carry out molecular texonomy. That correct identification is done by morphological characters and then the specimen is borcoded and the borcoded is submitted. If some one identifying based on barcode which is present in BOLD/ gene bank and the one who has submitted has missed correct identification, the exercise goes wrong. Therefore it is requested to go far correct identification seriously then only bar code and submit. If I have identified a specimen correctly and I try to match bar code of my specimen with already present in bold\ gene bank is wrong then i will land with many confusion like I will think mine is a new species.

Exception

An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions during the execution of a program.

When an error occurs within a method the method creates an object and hands it off to the runtime system. The object is called an exception object contains information about the errors including its type and the state of the program when the error occurred. Crating an exception object and handling it to the runtime system is called throwing an exception.
