Passage VII
The male-to-female body mass ratio (MFMR) of a species can be calculated as follows:
MFMR = Mm ÷ Fm
In this equation, Mm is the average body mass of adult males and Fm is the average body mass of adult females.
The figure shows the MFMR of some species within 4 primate groups: apes and humans; Old World monkeys; New World monkeys; and prosimians. A species with an MFMR of 1 is monomorphic with respect to body mass. A species with an MFMR different than 1 is dimorphic with respect to body mass. (Note: In the figure, MFMR values are calculated to the nearest tenth.)
36. According to the figure, the body mass of the average adult male orangutan is how many times greater than the body mass of the average adult female orangutan?
Your Answer is
Correct Answer is G
Explanation
Look at the picture on the upper left, the MFMR corresponding to O (orangutans) is 1.4
