Katydid Males Deliver Spermatophores To Females When Mating Spermatophores Deliver Both Sperm And Food Nutrients That 2 (18.07 KiB) Viewed 43 times
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′′=% times female approach was rejected by male; "\% Reject by F′′=% times female approached then rejected male; "\% with F-F comp." = \% female fighting over male observed.) Which of the following applies to the data presented above?
Males are more likely to call when females are more likely to mate Males are more likely to reject females when females are more likely to compete Females are less likely to mate when males are more likely to reject females Females are more likely to reject males when females have to compete
