Question

A group of organisms having many characteristics in common and ranking below a genus

Answer 1

is called a family. In biological classification, a family is a taxonomic rank that is higher than a genus and lower than an order. Families are groups of organisms that share a common ancestor and have similar characteristics. Each family is made up of one or more genera (plural of genus) that are closely related to each other. Families help scientists organize and classify living organisms based on their evolutionary relationships and shared characteristics.
