Chromosomal Aberration

Chromosomal aberration refers to a change in the normal structure or number of chromosomes—the structures that carry our genetic information. These changes can occur when chromosomes break, lose pieces, or when extra copies are made. Such abnormalities can lead to health issues, developmental delays, or genetic disorders, depending on which genes are affected. Chromosomal aberrations can happen randomly during cell division or due to environmental factors like radiation. They are a significant area of study in genetics because understanding them helps diagnose and potentially manage related health conditions.
