Kmer spectrum

[Gaurav_genomics]

The kmer spectrum plots the number of distinct N-bp sequences as a function of coverage level, placing low-coverage (rare) sequences at left and high-coverage, repetitive sequences at right.

Kindly make me understand what is the meaning of the x-axis and y-axis??..And what does this graph imply.??..What interpretation can we make from this spectrum??

From your description and the answer you received on biostars it sounds like you understand what the graph is showing. If you are looking for an in-depth biological interpretation, it is not possible from looking at k-mers alone. If you know the species, ploidy level, mating system, repeat content, etc. then you can explain the graph in biological terms, but otherwise it is not possible (that's probably why you didn't get an answer). The reason being that numerous biological factors could contribute to the k-mer spectra. Hope that helps.
