The Tasmanian native hen (Gallinula mortierii) is a flightlessbird in which males often outnumber females. In this system, eithera pair (male and female) raises offspring, or a trio (a pair helpedby a subordinate male) raises offspring. The subordinate male in atrio is usually the brother of the male of the pair. Given thefollowing data: a. First year breeding pairs with no helpersaverage 1.1 offspring produced during that year. b. First yearbreeding trios (Male and Female + subordinate male) produce 4.1offspring on average. c. Experienced pairs produce about 5.5offspring per year without helpers d. Experienced pairs withhelpers (i.e. a trio) produce about 6.5 offspring per year. If afirst year male is faced with three choices -- breed on its own,help a brother in his first year, or help an older, experiencedbrother -- which should it choose and why? Show your work andcalculations, and state which of the three options is best, secondbest, and worst. (Remember, helpers are helping raisenephews/nieces, not siblings).
