Based on this information, which of the following is likely the PRIMARY benefit of female choice in this newly discovered species? a) Parental care of young b) Resources c) Good genes d) None of the above 2. Sperm competition theory suggests that across species, male relative testes size (i.e. testes size divided by body size), should… a) …increase with female body size. b) …decrease with female body size. c) …increase with female mating frequency. d) …decrease with female mating frequency. e) …be highest in species with social monogamy. 3. You are investigating how neematodes ( Nickelodinus dougii ) in Lucky Duck Lake identify kin, whom they help. You’ve found that they make a learned “kaloo-kacoo” call, which varies among kin networks. Assuming they use this call to identify kin, which of the following is NOT a step in the recognition system? a) Members of a kin network hear the “kaloo-kacoo” call of nearby individual. b) Individuals make the “kaloo-kacoo” call as they approach a kin network.
