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.
