Question
What is chromosomal abnormality?
Answer
Chromosomal abnormalities refer to abnormal variations in the number or structure of chromosomes within the human body. These variations can lead to various diseases, including but not limited to developmental delays, deformities, and miscarriage. When there is an excess or deficiency in the number of chromosomes, or when the structure changes, it may affect the normal function of genes, thereby causing a series of health issues. In some cases, chromosomal abnormalities may be caused by genetic factors from parents, while in others, they may be due to environmental factors or other unknown reasons.
