Question
Chapter 11, Problem 2RQ
Summary Introduction
To explain:
The linkage of genes located on the same chromosome and separation of linked genes during meiosis.
Introduction:
The chromosomes consist of several genes and contain the genetic material. The chromosomes divide and separate during cell division. The numerous combinations of chromosomes lead to such a diverse variability in organisms.
