Subject: ADRC: 693B Dear Nam, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'waldo affects an early step in primordial germ cell migration.' You write about a new gene, wdo. Do you have a cytological location for wdo? It is nice if we can keep as many gene records anchored to the map as possible. Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC: 693B Dear Rachel, Thank you for your email regarding waldo. I am afraid the only definitive information regarding wdo's cytological location that I have is that it is located on 2L. I am currently mapping wdo. I will be sure to let you know once I have better information. Take care, Nam Cho
