Concept explainers
(a)
To explain: The consequences of non-disjunction in mitosis.
Concept introduction: A phenomenon in which there will be a failure of sister chromatids or homologous chromosomes to divide properly through the cell division (mitosis and meiosis) is called as chromosome non-disjunction. As a result of this phenomenon, some cells will have extra chromosomes (trisomy) or missing chromosomes (monosomy). Non-disjunction is one of the main reasons for the early spontaneous abortions.
