Summary Introduction

To explain:

How epialleles are different from genetic alleles.

Introduction:

Alleles are the alternative forms of a gene that expressed various observable phenotypic traits such as eye color, pigmentation, and height. The term allele derived from a Greek word ‘allelomorph’ which means the ‘other forms’ and the term was given by William Bateson and Edith Rebecca Saunders. Alleles may be recessive or dominant. A dominant allele is the allele that masks the contribution of the second allele present at the same locus. While recessive allele is the one which is being masked by the dominant and does not express itself.
