Abstract
The cornerstone of genetics is variation. No two individuals are alike, nor are their chromosomes. Heteromorphisms represent microscopically visible regions on chromosomes that are variable in size, morphology and staining properties in different individuals. Literally meaning “other or different forms”, the term “heteromorphism” is often used interchangeably with the terms “variant” or “polymorphism”. Polymorphism, however, is more correctly used in other contexts, implying multiple identifiable forms of a gene or molecule rather than of chromosome morphology. The term “normal variant” is often used, but is less precise. The main distinction is that heteromorphism can be seen under the microscope, whereas a polymorphism or normal variant might not. Because of widespread usage, both “normal variant” and “heteromorphism” are used interchangeably in this book. Heteromorphisms are typically stable, inherited and, by definition, every individual carries at least one form, if not two, for every heteromorphic region on their chromosomes.
