Your be Miscarriages are common and in the first trimester are usually due to chromosomal abnormalities. When cells form in reproductive organs, they start from one fertilized cell (sperm in males, eggs in females), then go through cell division (meiosis), where one cell splits twice to create four cells. Chromosomes are thread-like structures housed in the center (nucleus) of a cell that warehouse all the genetic information for each and every individual. Rarely, individuals with a very small number of cells with an extra chromosome 15 found on prenatal testing may have very few to no medical issues and live a normal life span. Each chromosome has unique regions or bands that contain genes, and each band is labeled numerically. Call your doctor or 911 if you think you may have a medical emergency.
