What is the genetic basis and phenotype for each of the following disorders (use proper genetic notation)?

  1.       a.            Edwards syndrome
  2.       b.            Patau syndrome
  3.        c.            Klinefelter syndrome
  4.       d.            Down syndrome

a.

Summary Introduction

To describe: The phenotype and genetic reasons related to Edward syndrome.

Introduction: Genetic disorders can prove to be fatal for various organisms. Expression of proteins takes place through genes present in an organism which are responsible for controlling the cells. Any fault in the gene can lead to physical deformities in an organism.

Explanation of Solution

A normal individual have two copies of chromosome in their genes. Development of an extra copy of chromosome of 18th chromosome causes Edward syndrome. In this disorder, 18th chromosome has 3 copies of chromosome leading to a condition of trisomy. The development of the organism is affected due to presence of this third chromosome. This leads to portrayal of signs and symptoms related to the disorder.

Weakness, delicateness and being underweight are common symptoms of Edward syndrome. Other phenotypic changes include prominent back of head, improperly formed low set of ears and small head, jaws and mouth...

b.

Summary Introduction

To describe: The genetic reasons and phenotypic changes of Patau syndrome.

Introduction: Genetic disorders are characterized by the abnormalities in the level of gene expression. These disorders are generally inherited from one generation to another. However, in many cases, these disorders can be acquired.

c.

Summary Introduction

To describe: The genetic causes and physical characteristics related to Klinefelter syndrome.

Introduction: A genetic disorder is characterized by the abnormalities in the genetic constitution of an organism. These disorders can result from several factors, but in most cases, these are inherited from the parental generation.

d.

Summary Introduction

To describe: The genetic basis and phenotype of Down syndrome.

The genetic reasons and physical characteristics of Down syndrome

Introduction:  Genetic disorders can prove to be fatal for various organisms. Expression of proteins takes place through genes present in an organism which are responsible for controlling the cells. Any fault in the gene can lead to physical deformities in an organism
