Document Summary
When parents and siblings weigh costs and benefits differently, conflict arises. Underlying trade-off with offspring-parent conflict: parents should maximize benefits- costs. Parents point of view: mother weighs costs of future offspring the same as current offspring, the costs of future offspring in a graph has a straighter line because the mother can produce many offspring. The offspring wants more than the parent is willing to give. Conflict over caring for a set of offspring each parent is equally related to offspring. Who should have to provide care: mammals females care, no male care. If it takes a long time to remate, benefits of deserting are low. If it takes a short time to remate, benefits of deserting are high. Results: high benefits for females in deserting, because they don"t take much time to find a new mate. Males care for offspring: kentish plover experiment #2. Low survival high cost of deserting because lowers reproduction.
