Genetic analysis

Genetic analysis refers to the process of studying and analyzing changes in chromosomes or genes using different methods in scientific fields such as genetics and molecular biology. It involves the localization and identification of genes and the detection of inherited or genetic disorders caused by mutations or other abnormal variations in our genome.
