Genetic disorders are diseases that are inherited. Sickle-cell anemia, cystic fibrosis, and Down syndrome
are three common genetic disorders. Choose one of these diseases and research the genetic basis of the
disease as well as how the disease can affect a person who inherits it.

Answer:

Down Syndrome

Explanation:

95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.

Down syndrome is a chromosomal condition that is associated with intellectual disability, a characteristic facial appearance, and weak muscle tone (hypotonia) in infancy. All affected individuals experience cognitive delays, but the intellectual disability is usually mild to moderate

Answer:

Cystic fibrosis is a genetic disorder that causes severe problems mainly on the respiratory system, but also on other organs such as the pancreas or the liver. It is an autosomal recessive disorder, meaning that an individual needs to inherit one copy of the gene from each parent in order to have the disease. The disorder is caused by a mutation in the gene that encodes the protein that participates in the transport salt intracellularly. This mutation causes a defect in the production of mucus, sweat and digestive fluid. In patients suffering from cystic fibrosis, these bodily fluids and the mucus are sticky and thick. This change in consistency causes severe damage to the respiratory and digestive systems.
