Table 3 Progeny of Cross A: XX x XY*

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

  1. aParental sources of the X chromosomes (Xm: maternal; Xp: paternal) are included in Tables 4, 5, and 6, since these crosses are also used to identify effects of parental X imprinting
  2. bFigure 3 illustrates the structures of the Y*, XY*, and Y*X chromosomes and the gene content of Y*X that includes the minute + subsegment of NPX that is also present in Y*. Note that the Y* and XY* PARs have a duplication of PAR regions A and B but lack PAR region C that encompasses the Sts locus
  3. cXmO are rare (~1% [75])
