| Front | Where are different alleles of the same gene positioned comparatively? |
| Back | They have different sequences of DNA but the same locus |
| Front | In what stages are ‘X shape’ chromosomes seen? |
| Back | Only during late prophase and metaphase, when the cell has replicated its DNA and is actively dividing |
| Front | Define homozygous recessive |
