Now the lab block does not contain a lot of information and is not intuitive to use.

It would be better if some more text could be added, in the form of titles or hover-over pop-up dialogs.

For example:

• Indicate that the top buttons represent chromosomes (chromosome 1, chromosome 2, ...).
• indicate that the middle buttons represent genes (gene 1, gene2, gene3,...) and top and bottom represent different alleles of those genes.
• indicate that the text at the bottom represents the sequence of these genes.
