I'm always interested in figuring out more of what's possible
do we know anything about what genes are on the same chromosome?
I was talking about that when we were discussing incompatible lines of...hypo I believe. (About the importance of knowing if they're on the same chromosome, not about crossing over, which can also be important)
The way I understand crossing over (and this is only from AP Biology, so I could definitely be wrong, although my Bio teacher was pretty much the best ever) is that it happens every time, but with only a few genes, so the location of the trait on the chromosome is really important.
Anyway, could be interesting...
