Genetic drift 

Genetic drift is an evolutionary force, in which allelic frequency change over generation Just by chance (sampling error). 

The deviations from the expected ratios are random, the direction of change is unpredictable.

NodA is an N-acyltransferase that catalyzes the addition of a fatty acyl chain.

NodB is a chitin-oligosaccharide deacetylase that removes the acetyl group from the terminal nonreducing sugar.

NodC is a chitin-oligosaccharide synthase that links N-acetyl-D-glucosamine monomers.
