A primer on the use of mouse models for identifying direct sex chromosome effects that cause sex differences in non-gonadal tissues

Table 8 Predicted expression of imprinted X genes

	If X^p = Xi	If X^m = Xi	Predict X gene expression in crosses
Maternal expression (paternal imprint)	Expression high	Expression low	FCG: X^mX^p < X^mY Cross A: X^mY^X = X^mY > X^mX^p = X^mX^pYCross B: X^mY > X^mX^p > X^pY^XCross C: X^mY* = X^mY*^X > X^mX^p
Paternal expression (maternal imprint)	Expression low	Expression high	FCG: X^mX^p > X^mY Cross A: X^mY^X = X^mY < X^mX^p = X^mX^pY* Cross B: X^mY < X^mX^p < X^pY^X Cross C: X^mY = X^mY*^X < X^mX^p
