chromosomes are composed of DNA and protein
genes are composed of chromosomes
organism cannot live withoutchromosomes
genes are located on the chromosomes and are transmitted to the next generation through them.

the percentage of crossing over between themis high
hardly any cross-overs detected
no crossing-over can ever take place between them
only double cross overs can take place between them.
