Ordered tetrad analysis
WebTetrad analysis can be used to confirm whether a phenotype is caused by a specific mutation, construction of strains, and for investigating gene interaction. Since the … WebTetrad analysis in animals is done by studying cases where more than one offspring is born at the same time. a and b a and c 4. Choose the correct ordering of the events in meiosis.
