A genetic disease is found in a family that affects the immune system, lungs, heart, and kidneys. A DNA analysis of several affected and unaffected family members determines that the disease is caused by a mutation in a single gene. What type of inheritance pattern is shown in this disease? (1 point)
The inheritance pattern in this disease is likely autosomal dominant inheritance.
Based on the information provided, the genetic disease that affects multiple organs and is caused by a mutation in a single gene is likely exhibiting an autosomal dominant inheritance pattern.
To determine the inheritance pattern of a genetic disease, we need to analyze the pattern in which the disease is passed on from one generation to the next. In this case, we are told that the disease affects multiple systems (immune system, lungs, heart, and kidneys) and is caused by a mutation in a single gene.
There are different types of inheritance patterns, including autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. Each pattern has its own characteristic way of being passed down through generations.
In this scenario, we are not provided with information about the gender specifically affected or unaffected, so we can assume that both males and females are affected equally. Additionally, we are not given any information about the affected individuals having affected offspring, so we cannot establish a pattern of transmission from one generation to the next.
Based on the information provided, the most likely inheritance pattern for this disease is autosomal dominant. Autosomal dominant inheritance occurs when a single copy of the mutated gene from either parent is sufficient to cause the disease. If an individual inherits the mutated gene, they have a 50% chance of passing it on to each of their children.
However, it's important to note that a thorough genetic analysis of the affected family members and a comprehensive family pedigree would be required to confirm the inheritance pattern definitively.
