In pea plants, the allele for purple flowers (P) is dominant and the allele for white flowers (p) is recessive. The allele for yellow seeds (Y) is dominant and the allele for green seeds (y) is recessive. The allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. These alleles segregate independently of each other. A plant with a PpYyRr genotype is crossed with a plant with a PpyyRr genotype. What is the probability that an offspring from this cross has at least two different recessive traits
