Tetrad analysis can be utilized to confirm irrespective of whether a phenotype is a result of a specific mutation, design of strains, and for investigating gene interaction.
Through prophase I of meiosis, one particular chromosome exchanges corresponding segments of genetic materials with one other chromosome from the tetrad in the method known as crossing above.
