A) X-linked disorders
B) mistakes occurring during mitosis
C) mistakes occurring during meiosis
D) recessive disorders

Question

Quizplus · Accepted Answer

Chromosomal defects typically result from mistakes occurring during meiosis, such as nondisjunction or translocation events. These errors can lead to abnormal chromosome numbers or structures, which can cause genetic disorders or developmental abnormalities in offspring. X-linked disorders are a specific type of genetic disorder caused by mutations on the X chromosome, but they are not the primary cause of chromosomal defects. Mistakes occurring during mitosis can also cause genetic abnormalities, but they primarily affect somatic cells rather than germ cells and do not lead to inherited disorders. Recessive disorders are caused by the inheritance of two copies of a mutated gene, rather than chromosomal defects.
