With regard to pedigree analysis, make a list of observations that distinguish recessive, dominant, and X-linked patterns of inheritance.

Expert Solution & Answer

Summary Introduction

To review:

The difference between recessive, X-linked, and dominant patterns of inheritance in accordance with the Pedigree analysis.

Introduction:

Pedigree analysis is the method used to determine the inheritance of genetic disorders. It is an important tool for studying the inherited disorders in the generations. The pedigree chart helps to visualize the relations between the large extended families.

Explanation of Solution

Differentiation between X-linked, dominant, and recessivepatterns of inheritance, according to the pedigree analysis are shown below:

Recessive inheritance	X-linked inheritance	Dominant inheritance
Affected offspring has unaffected parents.	Both, parents and offspring are affected.	Unaffected offspring have affected parents.
It is associated with autosomal genes.	Based on the X-chromosome genes.	It associated with the gene on the autosome.
Recessive traits affect females and males equally.	Traits skip generations to appear and males are more affected than females. Females are the main carriers of the disease.	Dominant traits affect both male and female offspring in each generation. Dominant X-linked is always passed on from father to daughter.

Conclusion

Therefore, it can be concluded thatX linked disease affects males, while in dominant inheritance, the disease affects the daughter. In recessive inheritance, both, the males and females have an equal chance of disease inheritance.
