Summary Introduction

To explain:

Anhidrotic ectodermal dysplasia is an X-linked recessive disorder: a. The reason that women which are heterozygous carriers of a recessive gene for anhidrotic ectodermal dysplasia have irregular patches of skin lacking sweat glands. b. The reason that the distribution of the patches of skin lacking sweat glands differ among the females, even among identical twins.

Introduction:

Anhidrotic ectodermal dysplasia is an X-linked recessive disorder in humans characterized by no sweat glands, small teeth and sparse body hair. This trait is generally seen in men and homozygous women. The carriers (females) of such trait often have irregular patches of skin with no sweat glands.
