In the nematode Caenorhabditis elegans, the mutations dpy-21(dumpy) and unc-34 (uncoordinated) identify linked genes that affect body conformation and coordination of movement. The frequency of recombination between the genes is 24 percent. If the heterozygote dpy-21 I unc-34 undergoes self- fertilization (the normal mode of reproduction in this organism), what fraction of the progeny is expected to be both dumpy and uncoordinated (assume dpy-21and unc-34 are recessive)
