It seems THAT is a topic of considerable discussion online actually.
T he platypus has ten sex chromosomes; males have an XYXYXYXYXY pattern while females have ten X chromosomes. Although it is an XY system, the platypus' sex chromosomes share no homologues with eutherian sex chromosomes.[17] Instead, homologues with eutherian sex chromosomes lie on the platypus chromosome 6, which means that the eutherian sex chromosomes were autosomes at the time that the monotremes diverged from the therian mammals (marsupials and eutherian mammals). However, homologues to the avian DMRT1 gene on platypus sex chromosomes X3 and X5 suggest that it is possible the sex-determining gene for the platypus is the same one that is involved in bird sex-determination. More research must be conducted in order to determine the exact sex determining gene of the platypus.[18]
They are not birds. The "duck" bill is an example of convergent evolution. They do not have feathers. They are not in any way "avian."
Their eggs are soft-shelled and leathery like a snake's, not hard like a chicken's.
The tail is shaped somewhat like a beaver's, but it's not actuallya beaver tail (to start with, it's furred); it's a rudder and a fat reserve, not a piece of construction equipment. This also does not mean that they are in any other way like a beaver. In particular they don't have buckteeth, or in fact teeth at all. Moreover, this means that their tails are not like that of the following species:They do not have breasts or nipples. They secrete milk directly through the skin. I suppose you could take some artistic license and make them a bit curvy but they still shouldn't have gigantic nipples with areolae.
Fox
Wolf
Squirrel
Dinosaur
Whatever the hell it is has long flowing locks of hair instead of a tail
Being monotremes (which literally means "one hole"), they have a cloaca, which the penis or vagina is hidden in. A hermaphroditic platypus would probably look just like a male platypus. They would not let it all "hang out."
Also, if you really must insist on drawing one in a state of arousal, the penis has four heads on it.
Who knew, lol? Even the simple platypus is a controversial figure.
Wouldn't that be part beaver?

They keep that buried in Platypus society.
