Can someone please explain me the difference between the two and how to pronounce them?I think it is this:

hoh-moh-je-nus for homogenous,

hoh-mo-jee-nee-us for homogeneous

But I have heard people pronounce the latter as the first and it feels weird to say hoh-mo-jee-nee-us. I have seen some stuff on youtube on this but they contradict each other haha. Is this another british/american english thing?
