What a difference a gene makes! For pigeons, one gene can make or break the appearance of fancy feathers.
Many pigeons have crests or collars, tufts of feathers on the
head or neck that appear to go the wrong way. They point up toward the
head instead of down toward the tail.
This funny feature decorates many
different pigeon breeds, but all of those birds have one thing in
common: a genetic change.
