The correct Answer is:
To identify the number of Mendelian disorders from the given list, we will analyze each disorder mentioned: 1. **Sickle Cell Anemia**: This is a genetic disorder caused by a mutation in the hemoglobin gene, making it a Mendelian disorder. 2. **Color Blindness**: This is typically an X-linked recessive disorder, which also qualifies as a Mendelian disorder. 3. **Thalassemia**: This is a genetic blood disorder caused by mutations in the genes that produce hemoglobin, making it a Mendelian disorder. 4. **Phenylketonuria (PKU)**: This is an autosomal recessive disorder caused by a mutation in the gene responsible for breaking down phenylalanine, thus it is a Mendelian disorder. 5. **Cystic Fibrosis**: This is an autosomal recessive disorder caused by mutations in the CFTR gene, making it a Mendelian disorder. 6. **Hemophilia**: This is an X-linked recessive disorder, which also qualifies as a Mendelian disorder. Now, let's summarize the findings: - **Sickle Cell Anemia**: Mendelian disorder - **Color Blindness**: Mendelian disorder - **Thalassemia**: Mendelian disorder - **Phenylketonuria**: Mendelian disorder - **Cystic Fibrosis**: Mendelian disorder - **Hemophilia**: Mendelian disorder All six disorders listed are Mendelian disorders. **Final Answer**: There are 6 Mendelian disorders in the given list.
