Association between Y-Maze Acquisition Learning and Major Histocompatibility Complex Class II Polymorphisms in Mice

Table 2

Relationship between acquisition and strain.

Strain	N	L	L%	χ^2	P
KM mice	55	19	34.5%	6.390	0.011
BALB/c mice	47	28	59.6%
TOTAL	102	47	46.1%	-	-

3-day slope: < 0 indicates learning; >0 indicates no learning. N: sample size; L: number of mice that have learned.
