    • ‘The first set showed a homology of 96 per cent.’
    • ‘Cross-species hybridization studies using human chromosome paints as probes reveal extensive homology.’
    • ‘A comparison of the sequences obtained from the amplified material revealed a complete homology to modern bacterial sequences.’
    • ‘Feathers also exhibit serial homology, in that the individual feathers are not distinguishable on any criterion.’
    • ‘The structures are so similar that homology is inferred.’
    • ‘The number of members per family may differ in various species, although they exhibit significant homology.’
