Genetic analysis is the study of an organism's DNA to understand its genetic makeup. This process involves examining specific genes or sequences to identify variations that may influence traits, health, or disease susceptibility. Techniques such as DNA sequencing and polymerase chain reaction (PCR) are commonly used in this field. Researchers use genetic analysis in various applications, including medical diagnostics, forensic science, and ancestry testing. By analyzing genetic information, scientists can uncover insights about inherited conditions, track genetic disorders, and even trace lineage. This information can help in developing targeted treatments and understanding evolutionary relationships among species.
