Which organisms show great synchrony between the sexes and release a large number of gametes into the surrounding medium (water)?
Bony fishes
Frogs
Birds
All of the above
Solution
Organisms exhibiting external fertilisation show great synchrony between the sexes and release a large number of gametes into the surrounding medium (water) in order to enhance the chances of syngamy. This happens in the bony fishes and frogs where a large number of offspring are produced.
