Imagine that horn color in Hodags (folkloric creatures of Wisconsin) is controlled by a single gene so that when you mate a Hodag homozygous for bright orange horns (COCO) with a Hodag homozygous for ivory horns (CICI), numerous offspring are produced, all with pale orange horns. Now consider that you cross an orange-horned Hodag with an ivory-horned Hodag and get an F1.
