Does Rooster or Hen determine gender?

Hi guys, this has probably been asked before, but, I'm keen to know if anyone knows!
does the Rooster or Hen determine gender?
For example in horses the stallion (father) determined the gender and some stallions throw more females than males and vica versa...
So has any studies ever been conducted? Does anyone know?

I have a hen who has had 12 pullets and 4 roosters (intensively monitored, recorded and incubated manually) to one Rooster.
Now we have put a new rooster over her and I'm keen to see if she has a high pullet hatch rate to this fellow or not!?
Chicks are only 2 weeks old from new rooster!

In birds, it's the female that will determine the sex of the offspring and in most mammals, the male will determine the sex. Fish, insects, and reptiles are a bit more complex!

I have always heard that it's the hen, and my experience backs that up.

The hen determines the sex of the offspring. Some lean male, some lean female.

Thanks for all your replies! Hopefully this hens pullets also throw high% of pullets.
