Among the Chromosomal Aberrations, there are structural (inversion, deletion, and translocation) and numerical (aneuploidy and euploidy). Chromosomal aberrations are changes in chromosomes that can often cause syndromes such as Down syndrome. Understanding this process is essential for the Enem and other entrance exams. Speciation is also a very important process that explains the differentiation in different species. The main processes are allopatric speciation and sympatric speciation.
