You discover a new bird species,but so far have only observed ten nesting females.The female birds are small and mostly brown,with a bit of red around their tails and throats.After the eggs hatch,you perform genetic tests which reveal that all chicks within a nest share the same father,but some chicks across nests also share a father.Based on this,what would you predict about the males of this species?
A)They will be larger than the females with more and brighter red coloration.
B)They will appear the same as the females.
