Mutant Fruit Flies That Make Only One Antimicrobial Peptide (Defensin

Mutant fruit flies that make only one antimicrobial peptide (defensin or drosomycin) were tested for survival after infection with Neurospora crassa fungi and the results are shown in the figure below. What statement about these data is true? Figure 35.1

A) No wild-type fruit flies die after being infected by the fungi.
B) Drosomycin protects fruit flies from N. crassi infections to a higher degree than does defensin.
C) Defensin is effective at preventing fruit fly infection by all fungal species.
D) After two days, approximately 65% of mutant + defensin fruit flies are dead.
