| Abstract: | Summary The possibility that male offspring are more costly to produce than female offspring was investigated in captive Macaca mulatta. Differential maternal investment into 187 infants was evaluated by comparing birth weight, infant growth rate, month of birth, and interbirth interval of males and females. There were no statistically significant differences between male and female infants for any of these variables. |
