INHERITANCE OF COAT-COLOR IN CATS 555 
of two years and three months it is in color almost the exact 
counterpart of its mother. It has, therefore, received from its 
mother the factor A’ while its three sibs have received the factor 
A for which the mother is presumably heterozygous, unless in- 
deed she is carrying non-agouti, a. The cross may be expressed: 
AAB’b x A’‘AB’b = 1 AAB’”? + 1 A’AB’? + 2 AAbb. Whether 
or not the two lined offspring are homozygous for B’ or carry 
6b is unknown. 
The dark-ticked lined male was bred to a very much ticked 
blotched female (14). This female had been brought in preg- 
nant and had produced (11) two blacks showing ghost striped, 
one blotched, and two striped. One of the striped had a very 
high degree of ticking. The skins of the others were not saved 
and no determination of the exact amount of ticking was made 
at the time. When bred to the dark-ticked lined male this fe- 
male produced four kittens—one lined and three blotched. The 
lined is shown in figure E and one of the blotched in figure F. 
The other two blotched were similar in amount of ticking to that 
shown in figure F. This female may then be considered as of 
formula A’abb. The cross to the lined male, AAB’b, gave 1 
A’AB’b and 3 A’Abb. Larger numbers would probably have 
shown some dark-ticked kittens. 
The same male was bred to the black and white female (2) 
mentioned under: the discussion of Siamese dilution. She had 
produced (4) by an unknown male two ghost blotched kittens— 
a black and a maltese-——-and two blacks in regard to which no 
ghost pattern was recorded. When bred to the lined male she 
produced (29) four kittens—three lined and one blotched. All 
the skins were kept and all were very dark. The mating may 
therefore be represented: #@ AAB’b X 2 aabb = 3 AaB’b + 1 
Aabb. 
The lined male was also bred to a black female (10) which 
showed indistinct stripes in her fur. She had produced (23) 
from an unknown male four black males, all showing stripes as 
ghost pattern. When bred to the lined male she produced (28) 
one lined and two striped kittens. The lined is shown in figure 
C and one of the striped in figure A. The other striped was
