WebIn ordered tetrad analysis, what is the maximum RF that you could observe between a gene and the centromere? (Hint: What RF would you observe between a gene and the centromere if the gene were distant enough from the centromere so that at least one crossover, and often more than onecrossover, occurs between them in every meiosis?) b. WebTetrad analysis can be used to confirm whether a phenotype is caused by a specific mutation, construction of strains, and for investigating gene interaction.
