Answer

Both cystic fibrosis and color blindness are inherited from parents to children.

Solution

Both cystic fibrosis and color blindness are genetic conditions that are typically inherited from parents to their children. Here's a brief overview of each: 1. **Cystic Fibrosis**: - **Inheritance Pattern**: Autosomal recessive. - **Description**: Cystic fibrosis is caused by mutations in the CFTR gene. A child must inherit two copies of the defective gene (one from each parent) to develop the condition. Parents who each carry one defective gene are typically asymptomatic carriers. 2. **Color Blindness**: - **Inheritance Pattern**: Most commonly X-linked recessive. - **Description**: Color blindness, particularly red-green color blindness, is usually inherited. Since the gene responsible is located on the X chromosome, males (with one X chromosome) are more frequently affected, while females (with two X chromosomes) are typically carriers unless they inherit two defective genes. **Conclusion**: Both cystic fibrosis and color blindness are inherited genetic disorders. Therefore, neither of them is "NOT passed from the parents to children." If the question intended to include additional options, please provide them for a more accurate response.

Mind Expander

Cystic fibrosis is a recessive genetic disorder, which means that a child must inherit two copies of the defective gene—one from each parent—to develop the disease. If only one copy is inherited, the child will be a carrier but won't show symptoms. On the other hand, color blindness is often inherited in an X-linked recessive pattern, primarily affecting males. However, some variants can be acquired through other means, like disease or injury, which makes understanding its inheritance a little trickier! As you dive deeper into the world of genetics, you might stumble upon fascinating real-world applications, such as gene therapy! This cutting-edge approach aims to correct defective genes responsible for diseases like cystic fibrosis, offering hope for more effective treatments and even potential cures. Imagine a world where a simple intervention can change a life defined by genetic challenges—how exciting is that?
