In genetics, the dash symbol (-) is a "wild card" that stands for either the dominant allele or the recessive allele; for example, R- means the individual has either the genotype RR or Rr. In Duroc-Jersey pigs, genotypes R- S- have a red coat color, R- ss and rr S- have sandy-colored coats, and rr ss pigs are white. R and S show independent assortment. What is the ratio of red : sandy : white among progeny of the cross Rr Ss × Rr Ss?
