Answer to Question #337574 in Genetics for roudi

Question

An extensive research program is underway in Los Angeles in order to obtain at least one specimen of Arabidopsis thaliana, a common weed that is resistant to salt and has violet flowers (a very rare characteristic). The allele determining resistance to saline media corresponds to SOS+ (Salt Overly Sensitive) and is dominant over SOS- (the plant becomes more sensitive to salt); on the other hand, the height is determined by the H allele, being recessive in stems exceeding 2.5 - 3 dm in height. What is the probability of obtaining the specimen that the experts are looking for from two trihybrid individuals, knowing that there is dominance for the three characters?
