And this is known as nondisjunction. So non disjunction is the process by which the chromosomes actually fail to separate correctly or equally during anaphase of either mitosis or mitosis. And this results in cells that have an incorrect number of chromosomes. So in human somatic cells, we know that if we begin with 46 chromosomes, we have to produce cells that also consists of 46 chromosomes and any variations to this number. For example, if we produce 45 chromosomes or 47 chromosomes, this leads to a condition known as anapply. Now, let's discuss how none disjunction actually takes place in mitosis as well as in meiosis.
