Why would female worker ants be more likely than other...

2. Do the calculations and answer questions by filling in the blanks. Workers in ants are infertile with workers never mating and thus cannot fertilize eggs to have diploid females. However, ant workers of some species can have males with unfertilized eggs because males are haploid. (a) In an ant colony with coefficient of relatedness of r = 0.75 between workers and new queens (monandry - queen of the colony mated with only one drone), what would increase the fitness of the workers more? Benefit (B) of raising reproductives (either sons by the worker or new queens) = 0.07, Cost (C) to own reproduction = 0.025. Answer using Hamilton's rule. (1) Worker helping to raise new queens: Br-C = ___ x ___ - ___ = ___ : Fitness ___ (increase or decrease) (2) Worker having own sons versus helping to raise (i) Nieces (r = ___) Br-C = ___ x ___ - ___ = ___ : Fitness ___ (increase or decrease) (ii) Nephews (r = ___) Br-C = ___ x ___ - ___ = ___ : Fitness ___ (increase or decrease) (iii) Brothers (r = ___) Br-C = ___ x ___ - ___ = ___ : Fitness ___ (increase or decrease)
