Genetic Disorders

Disorders can be inherited genetically, because of faulty genetic material, these are regarded as inherited or genetic disorders.

Examples

There are many examples of genetic disorders, I have documented the important ones.

Cystic Fibrosis

Cystic Fibrosis is a genetic disorder that affects cell membranes. It primarily affects the digestive and respiratory systems. Because of this, suffers have difficulties breathing and digesting food, as their organs get clogged by a think mucus.

It is caused by a recessive allele, this means that the disorder can be carried by people who do not suffer from the disorder themselves.

A genetic cross from cystic fibrosis might look something like this.

C c
C CC Cc
c Cc cc

From the genetic cross, you can establish that there is a 25% chance of being unaffected, 50% chance of being a carrier, and 25% of having the disorder.

Polydactyly

Polydactyly is a genetic disorder, that results in extra fingers or toes, that a human would typically have.

The extra finger or toes, causes the bearer no harm, and can be surgically removed after birth.
