Answer:
Chromosomal disorder is a condition caused by a change in the number or structure of chromosomes in a person's cells. Chromosomes are the structures in cells that carry genetic information in the form of DNA. Different types of chromosomal abnormalities can occur, including missing or extra chromosomes, rearranged chromosomes, and changes in the structure of individual chromosomes. These abnormalities can lead to a variety of health problems, including developmental delays, intellectual disability, and physical abnormalities.
Chromosomal abnormalities can arise in different ways, including errors in cell division during development or exposure to certain chemicals or radiation. Some chromosomal abnormalities are inherited from a parent, while others occur spontaneously during the formation of reproductive cells or early development.
The prognosis for individuals with a chromosomal abnormality depends on the specific type of abnormality and the severity of associated health problems. Some individuals with chromosomal abnormalities can lead relatively normal lives, while others may have significant developmental or health issues that require ongoing care. The survival rate for individuals with chromosomal abnormalities varies widely, but advances in medical care and technology have improved outcomes for many affected individuals. Hope this helps.
