A gene is the basic physical and functional unit of hereditary. Every person has two copies of each genes, one inherited from each parent. For instance, blue colored eyes are considered a recessive gene. The most common question asked about eyes is, "What color will my baby's eyes be?"
Genes come in pairs, and each gene in a pair may differ slightly. One gene may be dominant, and override the other gene. A recessive gene …show more content…
Us as a person, we have up to 46 chromosomes divided equally between the mother and father. The child therefore gets 23 chromosomes each from both parents.
Genes are like the building blocks of hereditary; every child inherits genes from both of their biological parents. Some traits are physical such as: eyes, hair and skin color. The downside is that the offspring could inherit disorders or diseases that lie beyond the family.
A genetic disorder or disease is an inherited medical condition caused by a DNA abnormality. The most common types of disorders/diseases include: Down Syndrome, Cystic Fibrosis, Huntington's Disease, Sickle Cell Anemia, and Hemophilia. Below, I will attach each disease/disorder with its definition.
• Down Syndrome: a genetic chromosome disorder causing development and intellectual delays
• Cystic Fibrosis: an inherited life threatening disorder that damages the lungs and digestive system
• Huntington's Disease: an inherited condition in which nerve cells in the brain break down over time
• Sickle Cell Anemia: a group of disorders that cause red blood cells to become misshapen and break down
• Hemophilia: a disorder in which blood doesn't clot
