In the plant arabidopsis thaliana, a geneticist is interested in the development of trichomes (small projections). a large screen shows two mutant plants (a and b) that have no trichomes, and these mutants seem to be potentially useful in studying trichome development. (if they were determined by single-gene mutations, then finding the normal and abnormal functions of these genes would be instructive.) each plant is crossed with wild type; in both cases, the next generation (f1) had normal trichomes. when f1 plants were selfed, the resulting f2's were as follows: f2 from mutant a: 602 normal; 198 no trichomes f2 from mutant b: 267 normal; 93 no trichomes i. explain what these results show, including proposed genotypes of all plants in your answer.

Sally, age 3 months, has a moist, red, vesicular rash on her cheeks, the backs of her hands, and her arms. her mother said sally was constantly trying to scratch the rash and often has difficulty sleeping. her father has a family history of allergic rhinitis and asthma. discussion questions. 1. review atrophic dermatitis from chapter 3 and discuss the pathophysiology of sally’s symptoms. 2. why is the father’s medical history significant, and what can sally expect as she grows up? 3. discuss the need to limit scratching, and describe practical methods to achieve this.
