Summary: KIWI PHOTO Palmerston North ACADEMIC WORD A homogenous (or homogeneous) population has little variation between members. So that means that each member is quite similar to the others. ‘Homo’ means ‘same’ and ‘genus’ means ‘type’ in Greek. The opposite is ‘heterogenous’, which means ‘different types’. So a heterogenous population has a lot of variety. The nouns are ‘homogeneity’ and ‘heterogeneity’, which means ‘sameness’ and ‘diversity’. TEST Here are FOUR sentences with the word of the day. But only THREE are correct. Which is the Odd One Out? The custom of rubbing noses is more or less homogenous to handshakes and embraces in Western cultures. The students in the class were far from homogenous, which made it difficult to decide on what they knew and needed to know, as well as how best to help them learn it.

The model assumes homogenous capital markets, which does limit its application to complex real world contexts.
