The trait for medium-size leaves in iris is determined bye the genetic condition PP'. plants with large leaves are PP. while plants with small leaves are P'P'. the trait for red flowers is controlled by the gene RR, pink by RR', and white by R'R'. A cross is made between two plants each with medium-size leaves and pink flowers. if they produce 320 seedlings, what would be the expected phenotypes, and in what number would the y be expected? assume no linkage.
