You quantify mean egg size for three species of fish. For species A, mean egg size is 0.6 mm diameter; for species B, mean egg size is 0.4 mm diameter; and for species C, mean egg size is 0.2 mm diameter. Based on the life history data collected by Vila-Gispert, Moreno-Amich, and García-Berthou (2002), what prediction can you make about relative levels of parental care in these species?
A) A will most likely exhibit the greatest level of care. B) B will most likely exhibit the greatest level of care. C) C will most likely exhibit the greatest level of care. D) All species will exhibit the same low level of care. E) None of the species will exhibit parental care.
Which of the following is predicted by sexual conflict theory?
A) The sex with the more efficient immune system should provide more care. B) The sex that is larger should provide less parental care. C) The sex that is larger should produce the smaller gametes. D) The sex with the higher cost of parental care should provide less care. E) The sex with the higher cost of care should have the longer life span.
