Materials: M&M candies, small plastic bag, paper towel, calculator. Procedure: 1. WebIn the case of de novo mutations, our simulations reveal that there is a considerable risk that they are directly lost again through drift since they are on average initially much rarer than mutations that are part of standing genetic variation (Fig. 5 A and C and SI Appendix, Fig. S10 A and C), added to the possibility that some TSR mutations ...
