A genetic disorder is a condition that is caused by an abnormality in an individual's DNA. There are different types of genetic disorders, and these can be either chromosome disorders, single gene disorders, or multifactorial disorders. How well did you understand them all? Take up these basic questions on genetic disorders and see how well you understood the topic. All the best!
