Here’s a portrait of Sebastian from early May. He was a little sleepy, but his blank, wet, wide open eyes reveal an amazing play of colours. The ring of deep blue that dominated his eyes when he was born is gradually being  pushed out of the way by a ring of brown spreading out from his pupil. There’s no doubt he inherited his mother’s eyes, both in size and colour. Her’s, however, were were brown from she was born; here, the brown has to assert dominance over the blue in a long drawn out war of positions. It seems inevitable, though, that the brown shall win; to the blue belongs but certain defeat, though not without honour, holding out so long against the dominant brown allele.
