🧬Genetic disorders are caused by changes in DNA sequence, resulting in abnormal chromosomes.

🔄Aneuploidy is a common type of genetic disorder caused by the abnormal number of chromosomes.

🌱Polyploidy, which involves having more than two sets of chromosomes, is common in plants.

👶Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21.

♀️Turner syndrome is a chromosomal disorder that occurs in females, resulting in various physical and developmental abnormalities.

Can genetic disorders be prevented?

—While not all genetic disorders can be prevented, certain measures such as genetic counseling and prenatal testing can help identify and manage the risk of certain disorders.
