Respuesta :
The result of an error in anaphase that failed to separate a pair of sister chromatids, one cell would have an extra chromosome, and one cell would lack a chromosome.
Anaphase, is that the stage of mitosis after the method of metaphase, when replicated chromosomes are split and newly-copied chromosomes are moved to opposite poles of the cell.
In anaphase, the sister chromatids become independent from one another and are pulled towards opposite ends of the cell. The protein "glue" that holds the sister chromatids together is weakened, allowing them to separate. Each is now its own chromosome. The chromosomes of every pair are pulled towards opposite ends of the cell.
During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell. pulled by microtubules. In nondisjunction, the separation fails to occur causing both sister chromatids or homologous chromosomes to be pulled to one pole of the cell.
