Lyretail mollies, female or male?

[BlueAndBlack]

Hello
So I have a black lyretail molly and a golden dust lyratail. I bought both as females and I also have two other mollies who are definitely female (both were pregnant and had fry). But the two lyratails were never pregnant in the almost three months I already have them (and they were in the shop together with males, it was a mixed tank my other two females weren't in a tank with males but are nevertheless pregnant). Also the black lyretail often chases my female black molly (she just gave birth to her fry today and especially now I have the feeling that the chasing got more, or I maybe just notice just now more
And here are pictures of them:

Are they really female because I can't really belive it anymore.
Also they are like 7 cm long, that is like almost three inches I think. (also I googled that would be the exact size for the males)
Thank you for replies!

I think the top one is male. The bottom is female. I'm not 100% sure, but I think it's right.

Oh tank you! Now if you don't mind I would like to ask another related question. Is lyratail a more prominent gene, so is my fry more likely to have a fancy fin like that or are they more likely to have "normale" fins? Or is that something that you can't really tell and you just have to wait and see?

I honestly have no idea.

Can't really tell wether the black one is male or female for it's not clear wether it's having a clamped analfin or a gonopodium. The gold dust one is definitely a female.
