a. Female acquisition of resources from male b. Female consensus for male "sexy" trait c. Heritability for female preference d. Heritable "sexy" male trait 16. All f the ollowing are preconditions for the Sexy Son hypothesis except: Katydid males deliver spermatophores to females when mating. Spermatophores deliver both sperm and food nutrients (that the female actively eats). Use the information in the graph below to answer the questions that follow. ("Control" low food treatment, "Extra'" high food treatment; "Calling males": # of males calling, "Matings/female"-# times females mated; "% Reject by M"-X times female approach was rejected by male; "% Reject by F": % times female approached then rejected male; 1% with F-F comp."-96 female fighting over male observed.)
