Chatelaine (ginger Manx cat) and Tropea (dilute tortoiseshell cat)

2014

A ginger Manx cat and a dilute tortoiseshell in a shelter. A 2013 study found three single-base-pair deletions and one duplication-deletion in the T gene across independent Manx lineages in the United States and on the island itself, each truncating the Brachyury protein.
