Question

In Anis, cuckoo-like birds, two females sometimes lay eggs in a single nest. One female is dominant and controls the nest, including which eggs are incubated. For this question, assume that the dominant can (1) distinguish which eggs are her own and (2) throw out the eggs of the subordinate female. A single female can raise 3 offspring successfully; a pair of females can raise ten. (Do not do outside research on this. The reality is more complicated than the scenario provided and you'll just confuse yourself.) Again, let's assume that the subordinate lays 10 eggs and the dominant lay 10 eggs but only 10 of the 20 can stay in the nest thus the dominant will kick out 10 eggs. Using the appropriate calculations, determine how many of the subordinate's eggs will dominate throw out and how many will she keep if:

the two females unrelated?

the two females are full sibs?

Using Hamilton’s rule, explain how inclusive fitness accounts for these relationships
