#karyotypinganalysis

Advancements in chromosome analysis allow for early detection of thalassemia major and sickle cell disease in babies before birth. Tissue sampling through chorionic villus biopsy or amniocentesis helps diagnose these conditions with 98-99% accuracy using molecular techniques like PCR, microarray, and sequencing. Similarly, chromosomal analysis (karyotyping) can identify genetic conditions in parents, helping prevent the birth of babies with conditions like Down syndrome through careful prenatal strategy.
