Chapter 17, Problem 6SA
Summary Introduction
Introduction:
In a single population, variations in a single gene can be seen. These variations are caused because of presence of two or more alleles of the gene which is responsible for that trait. Even after presence of traits, similarities to some extent are maintained in different populations. Maintenance of similarities between populations can help in their interaction with each other if living in similar habitats..
