Imagine that the selection coefficient (s) against a harmful recessive allele (which occurs at a frequency q = 0.01), changes from s = 0.5 to s = 1. what effect will this change have on delta p (the change in the frequency of the dominant allele from one generation to the next)? calculate delta p at s= 0.5 and s = 1.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
