Can female guppies decides what to give birth to the most of?

Question

It seems all I have is females and not any male guppies in that tank of mine, I started off with one male and four female guppies 7 months ago, and so I am wondering if a female guppy can decide which to give the most birth too, no males and more females, Can this happen?

Answer 1

My local fish store told me that the gender of guppies is determined by the temperature of their tank, as baby fry. I am not sure if this is true, but my guppies were almost always females and I think it was because the heat was to high.

Answer 2

well i think so yes
try go head
best of luck
