Deletion [Del(c)]	m
	5961SB	6287SB
Del(c)14CoS	0/40* (5)†	0/422 (8)
Del(c)10R75M	0/30 (7)	3s/42 (11)
Del(c)112K	0/31 (1)	0/23 (10)

^*The ratios represent the number of albinos present at weaning (25% expected) over the total number of progeny born from the cross c^ch +/Del(c) × c^ch +/c m. “n” designates albinos that were externally normal, and “s” designates albinos that were runted. 

^† Number in parentheses gives the number of albinos present at birth. Albinos are distinguished at birth by the absence of eye pigment. 

^‡ Six nonalbinos, in addition to the four albinos indicated, were also lost between birth and weaning.
