Chromosomal Abnormalities
Chromosomal abnormalities refer to changes in the number or structure of chromosomes, which are the thread-like structures in cells that carry our genetic information. These abnormalities can occur due to errors during cell division, leading to conditions such as Down syndrome, where an extra chromosome 21 is present. They can also arise from deletions, duplications, or rearrangements of chromosome segments. Such changes can impact a person's development, health, and physical traits, potentially leading to various medical issues. Understanding these abnormalities is essential for diagnosis, treatment, and genetic counseling.

Chromosomal abnormalities are changes in the number or structure of chromosomes, which are the thread-like structures in our cells that carry genetic information. Normally, humans have 46 chromosomes arranged in 23 pairs. Abnormalities can lead to too many or too few chromosomes or to alterations in chromosome structure. These changes can result in genetic disorders, affecting development, health, and function. Common examples include Down syndrome, caused by an extra copy of chromosome 21, and Turner syndrome, resulting from a missing X chromosome in females. Such conditions highlight the importance of chromosomal integrity for normal biological function.
