were closely linked to the iris and (6) show / showed high accuracy in transforming brown eyes into blue. Our use of flanking and background markers (7) considerably enhances / has considerably enhanced / considerably enhancedthe success rate, saving time compared with conventional backcrossing schemes, to achieve the same results. The effectiveness of XYZ plus backcrossing (8) has been / was confirmed by evaluating the performance of five PQR lines. Based on selected physiological and growth parameters, the newlines) are / were similar to those achieved with more expensive methods. The results of this study (10) con firm have confirmed confirmed bi the enormous benefits of the applications of XYZ in transforming eye color and thus leading to a 77% greater chance of success in presidential elections. CONCLUSIONS We (11) describe / have described / described the use of XYZ associated with marker-assisted backcrossing. We (12) believe /
