Research and write a brief description of each genetic disorder. 2. For each disease, state the chances that a child would be born with the disease: – if one parent carries the gene; and if both parents carry the gene. Explain how you arrived at your answers. Use Punnett squares to help justify your response for each disease. Genetic Disorders Exploring Disease Risk Factors and Inheritance Patterns

Gene Disorders Exploring Disease Risk Factors & Inheritance Patterns 

Genetic disorders are caused by mutations in a person’s DNA and can be passed down from parent to child. Understanding the risk factors and inheritance patterns of genetic disorders will help individuals make educated decisions about their health and family planning. We will be discussing two genetic diseases, Cystic Fibrosis and Down Syndrome. Also, the likelihood that a child may inherit the disorder if either one of the parents has the gene. A mutation in the CFTR genes causes Cystic Fibrosis, an autosomal recessive condition. This gene produces a protein which regulates the movement of water and salt in cells. The chance that a parent has CF is 25% if they both have the mutated genes. This means their children will inherit two copies. This inheritance pattern can be visualized using a Punnett Square. The Punnett square calculates whether the children will inherit one or two of their parents’ mutated genes. Down Syndrome, a genetic disorder characterized by an extra copy 21 of the chromosome 1, is caused by chromosomal mutations. The child is born with a copy of chromosome 21 if both parents are carrying it. Cont…
