Which of the following is not a genetic disorder?
Correct answer: D. Epilepsy
- A. Hemophilia
- B. Color blindness
- C. Phenylketonuria (PKU)
- D. Epilepsy
Explanation
Epilepsy is identified as a neurological disorder characterized by recurrent seizures and is not classified solely as a genetic disorder, as it can result from numerous non-genetic factors such as brain injury or infection. On the other hand, hemophilia, color blindness, and PKU are explicitly genetic disorders caused by specific gene mutations or hereditary transmission through chromosomes.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
