Drawings of Nondisjunction

The diagrams that follow show nondisjunction during mitosis, meiosis I and meiosis II in a species that has a diploid chromosome number of 8.

	Prophase
	Metaphase
	Anaphase
	Telophase Notice that the cell forming on the left has an extra chromosome and the cell forming on the right has a chromosome missing.
	G₁ Interphase During this phase, the chromosomes uncoiled and not visible.
	G₂ Interphase During this phase, the chromosomes uncoiled and not visible.

	G₂ Interphase During this phase, the chromosomes uncoiled and not visible.
