        Aneuploidia é um tipo de anomalia cromossômica. Uma aneuplóide teve o seu material genético alterado, sendo portador de um número cromossômico diferente do normal da espécie, isto é, o cariótipo de uma dada célula pode ter cromossomos a mais ou a menos (por exemplo, um ser humano com aneuploidia estará fora da normalidade de 22 pares de cromossomos + 2 cromossomos sexuais). As alterações ocorrem no número de cromossomos, porém, não em to…
