1. The dpy-5 gene is on Chromosome I, rol-6 on Chr II, and him-5 on Chr V. We know that the mutation for him-5 is recessive. You need to find out whether dpy-5 and rol-6 is recessive or dominant. The him-5 males carry no mutation for dpy-5 or rol-6; in other words, they have the wildtype genotype for the dpy-5 and rol-6 loci. a. In your dpy-5* him-5 cross, if dpy-5 is dominant, what do you expect to see in your F1 progeny? If dpy-5 is recessive, what do you expect? b. In your rol-6 * him-5 cross, if rol-6 is dominant, what do you expect to see in your F1 progeny? if rol-6 is recessive, what do you expect?

Question
Transcribed Image Text:1. The dpy-5 gene is on Chromosome I, rol-6 on Chr II, and him-5 on Chr V. We know that the
mutation for him-5 is recessive. You need to find out whether dpy-5 and rol-6 is recessive or
dominant. The him-5 males carry no mutation for dpy-5 or rol-6; in other words, they have
the wildtype genotype for the dpy-5 and rol-6 loci.
a. In your dpy-5* him-5 cross, if dpy-5 is dominant, what do you expect to see in your F1
progeny? If dpy-5 is recessive, what do you expect?
b. In your rol-6 * him-5 cross, if rol-6 is dominant, what do you expect to see in your F1
progeny? if rol-6 is recessive, what do you expect?
