Fig. 5.1 shows different stages of meiosis in an animal cell. Stage A shows the chromosomes (two long, two short); in stage B the chromosomes are in homologous pairs; stage B produces two cells at stage C, which each produce two cells at stage D.

1. aState the diploid number of chromosomes of the animal cell in stage A. [1]
2. bSuggest a name of an organ in a mammal where the different stages of meiosis take place. [1]
3. cName the stage of cell division shown at B and give one reason for your answer. [2]
4. dDescribe the chromosomes that could be found in all cells at stages C and D (draw them on paper). [4]

You'll mark your own answer against the marking guide when you hand it in.
