Biosystematics aims at:
 

1.	The classification of organisms based on broad morphological characters
2.	Delimiting various taxa of organisms and establishing their relationships
3.	The classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies
4.	Identification and arrangement of organisms on the basis of cytological characteristics

Which of the following taxonomic category is less general in characters as compared to the taxonomic category ‘Genus’?

Which arrangement is in correct ascending order?

Which one of the following belongs to the family Muscidae?
