Na plant, a single locus affects both berry color and berry size. there are two mutant alleles (r1 and r2) in addition to the wild-type allele (r0). individuals that are r0r0 have large, white berries. individuals that are r1r1 or r0r1 have red berries, individuals that are r2r2 or r0r2 have small berries, and r1r2 individuals have berries that are both red and small. what are the expected phenotypic ratios if you crossed r1r2 individuals to homozygous wild type?

Ms. w, a 21-year-old woman, came into a clinic after suffering a deep laceration on her foot while walking barefoot around her yard. the wound was cleaned, sutured, and bandaged, and she was released to return home after receiving tetanus antitoxoid. within 72 hours, the wound area was red and swollen, the suture line was dark in color, and it was accompanied by severe throbbing pain. ms. w had a high fever, her heart felt like it was racing, and she was finding it hard to concentraten even on simple tasks. she returned to the clinic and was immediately taken to the hospital. following lab tests, a diagnosis of acute necrotizing fasciitis was made. discussion questions 1. explain why ms. w. received a tetanus antitoxoid before leaving the hospital. (see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?
