Answer:

Non-N-fixing plants usually benefit from reduced competition in mixed stands compared to pure stands and attain higher biomass and N content per plant

Explanation:

a plant that has a pure trait is homozygous. homozygous traits are either a combination of two dominant alleles or the two recessive alleles. a hybrid would be the opposite, consisting of dominant and recessive alleles, therefore making it unpure (lol sorry) and hybrid.

i hope that made sense!
