Figure 1: Pedigrees of control crosses between Line3 and mice carrying the Avy allele.

(a) Schematic of experimental setup of Avy crosses. (b) Coat colour of offspring from crosses between wild type (Line3) sires and pseudoagouti (Avy) dams. (c) Coat colour of offspring from crosses between pseudoagouti (Avy) sires and wild type (Line3) dams. Data were produced from at least five different mating pairs in each case. Offspring not carrying the Avy allele have been omitted.
