A sharp-tailed (ST) male spontaneous mutation is found in your… A sharp-tailed (ST) male spontaneous mutation is found in your worms. You mate this ST mutant to wild type females, and see that all F1 females are Sharp-Tailed, and all males are wild type. 1) What is the mode of inheritance for ST? Please briefly explain. 2) You make a stock of pure-breeding ST and carry out a three factor cross to map ST with respect to the markers green (g) and red (r). You cross ST males to g r females, then take the resulting F1 females and cross them with r g males. Because ST is dominant, you observed its presence or absence in recombinant types directly in the F2 generation. You identify 10 Green recombinants and 10 Red recombinants. All Green recombinants had Sharp Tails, and none of the Red recombinants had Sharp Tails.With this information, draw the most likely map order diagraming the recombination events that would have resulted in the Green and Red reombinations.
