Figure 1. Illustration of the breeding scheme used in the mapping cross. The BALB/cByJ and C57BL/6ByJ parental strains are crossed in both directions. The resulting F1 mice are inbred through brother–sister mating to produce the F2 generation. This figure shows the manner in which the Y chromosomes and recombined (black and white-striped) and unrecombined (solid color) X chromosomes are passed through the generations of the cross. White chromosomes are inherited from the BALB/cByJ albino parent, and black chromosomes are inherited from the C57BL/6ByJ pigmented parent. The different coat colors shown in the F2 generation are for illustrative purposes only. The color of the F2 animals is unrelated to either gender or the direction of the cross.
