Grapes are a type of fruit that grow in clusters of 15 to 300, and can be crimson, black, dark blue, yellow, green, orange, and pink. "White" grapes are actually green in color, and are evolutionarily derived from the purple grape. Mutations in two regulatory genes of white grapes turn off production of anthocyanins, which are responsible for the color of purple grapes. Anthocyanins and other pigment chemicals of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines. Grapes are typically an ellipsoid shape resembling a prolate spheroid.
What gene makes grapes purple?

Victoria later described her childhood as "rather melancholy". Her mother was extremely protective, and Victoria was raised largely isolated from other children under the so-called "Kensington System", an elaborate set of rules and protocols devised by the Duchess and her ambitious and domineering comptroller, Sir John Conroy, who was rumoured to be the Duchess's lover. The system prevented the princess from meeting people whom her mother and Conroy deemed undesirable (including most of her father's family), and was designed to render her weak and dependent upon them. The Duchess avoided the court because she was scandalised by the presence of King William's bastard children, and perhaps prompted the emergence of Victorian morality by insisting that her daughter avoid any appearance of sexual impropriety. Victoria shared a bedroom with her mother every night, studied with private tutors to a regular timetable, and spent her play-hours with her dolls and her King Charles spaniel, Dash. Her lessons included French, German, Italian, and Latin, but she spoke only English at home.
What was Victoria's cat's name?
A: unanswerable
