Summary Introduction

To determine:

The differences between the penetrance and expressivity.

Introduction:

From person to person the expression of the genotypes of a gene varies. This variance is because of the results of the presence of other genes and the environment. Though the genetic makeup of the identical twins is same, however, they have differences in their phenotypes. The distinction in the expression of the genotypes is described by the terms pleiotropy, expressivity, and penetrance.
