Eusociality is always driven by a haplodiploid genetic system.
False
In Dr. Adams example, what context dependent factor determined whether "guest ants"
were mutualists instead of parasites?
"Raider" ants
What is Hamilton's Rule?
If relatedness times the benefit of helping a relative exceeds the cost of helping a relative then
altruism will occur
Zooxanthellae living in coral are an example of a ____ mutualism:
Trophic mutualism
In a species of fish, males with tall dorsal fins have increased survival. Length of the caudal
fin has no effect on male survival. Which of these traits would be better as an honest signal
of 'good genes'?
Dorsal fin, with males with tall fins having the 'best' genes
, In a haplodiploid system, calculate a) the relatedness of a maternal aunt (sister to the
mother) to a focal son (__________) , b) the relatedness of a paternal aunt (sister to the
father) to a focal son (__________), and c) determine which aunt is most likely to help raise
the focal son (________).
a. 0.375

Strategies are dynamic (not fixed)
When is Hamilton's Rule NOT likely to be true?
Relatedness is low
Is the following statement true or false about Evolutionary Stable Strategies (ESS)?
