I don't know chromosomes very well but i know genes and DNA. Genes are microscopic relations between 2 things. for example, if you had a twin you would have very similar genes making you even more related. As long as your related to them by genes they are a bit of your family. DNA is basically the building blocks of life as we've learned from the jurassic park movie, that nothing can exist without DNA. In other words DNA is your very essence, its every single tiny speck that makes you. But again i don't know too much about chromosomes, your on your own there<span />
