Genome composition is used to describe the make up of contents of a haploid genome, which should include genome size, proportions of non-repetitive DNA and repetitive DNA in details. By comparing the genome compositions between genomes, scientists can better understand the evolutionary history of a given genome.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): By comparing repetitive DNA, what can scientists understand the history of?
