Packet B: Tossup 18

Studies of this trait in response to an event in Lagerlunda led Frithiof Holmgren to develop his namesake wool. A book titled for this trait, which analyzes both lytico-bodig disease in Guam and the prevalence of this trait on the Pingelap Atoll, is by Oliver (10[1])Sacks. (-5[1])By analyzing (10[1])Homeric epithets, (10[1])William Gladstone dubiously concluded (10[2]-5[1])that the Ancient Greeks (10[4])had (10[1])this trait. (10[10]-5[3])Mark (-5[1])Zuckerberg’s (10[6])possession (10[1]-5[1])of a (10[1])form of this trait partly inspired (10[2])Facebook’s (10[1]-5[1])logo. (10[3])This trait (10[1])was historically called (-5[1])Daltonism (10[4])in reference (10[4])to (10[2])John (10[1]-5[1])Dalton, (10[3])who had a form (10[2])of it (10[1])called (10[2])deuteranopia. (10[5]-5[1])This (10[1])trait (10[1])can be (10[1])detected (10[2])via an Ishihara test, in which (10[2])a number is written in a circle (10[1])of dots. (10[2])For 10 points, what trait that can be caused by missing or deficient cone cells includes the congenital “red–green” form? (10[1])■END■ (10[3])

ANSWER: color blindness [or colorblindness; or color vision deficiency; or color deficiency; or CVD; accept achromatopsia; accept specific forms of color blindness like deuteranopia or monochromacy or red–green color blindness until read; prompt on color vision or eyesight] (Sacks’s book is The Island of the Colorblind.)
