The rough gray phenotype suggests that the genotype for fur texture is homozygous recessive (since smooth is dominant), and the gray color indicates a heterozygous genotype for fur color (since black and white are incompletely dominant, resulting in gray when combined). Crossing two rough gray individuals (rrBb x rrBb) would produce offspring with a 1:2:1 ratio of black:gray:white in fur color, all with rough texture, because the rough texture is homozygous recessive and not affected by the cross.
