It is very hard to see the flowers from your image. Agree with Kellie, generally the male tree produces only male flowers which are hanging down from stalks. The flower look like long bell shape with filamentous anthers.
Female tree produces only female flower which are white or yellow in color with visible ovary at the base , stamens in the middle but without stigma.
The bisexual or hermaphroditic papaya tree produce flowers which contain both male and female organs. This flower usually emerge from bases of the leaves with ovary and stamens.
Some may produce individual male and female flowers in the same tree which don't require other tree for pollination.
