3) Use your diagrams or photos to describe the behaviour of chromosomes in mitosis and meiosis
(M2). Explain clearly why you have chosen each cell to represent each of the different stages.
3. The cells shown in the diagram are in various stages of mitosis or meiosis. All the cells come the same
individual (a mammal).

in this animal?
(b) Give the names of each stage shown.
