Chapter 21.5, Problem 2CYP
Summary Introduction
To determine:
If a woman affected by an X-linked dominant disorder can have a child who is not affected.
Introduction:
X-chromosome is one of the two sex chromosomes present in humans. The other counterpart of the X-chromosome is the Y-chromosome. The combination of these two sex chromosomes gives different sex to organisms. The inheritance of genes present on the X-chromosome is said to be X-linked and this type of inheritance is known as X-linked inheritance.
