If you are a graduate student or postdoc and are wondering how you might make a significant contribution, I recommend assembling an online database to be made freely available. In particular, a database of chromosome numbers for animals would be very useful, and I don’t mind if you start out with the limited sampling of karyotype information that I have included in the Animal Genome Size Database. Why not start with, oh I don’t know, butterflies, and then let me see the dataset once you have it compiled? Anytime in the next week or so would be great. Not that I am trying to do a comparison of chromosome numbers in butterflies or anything.
