I just recently joined GCAS. I found quite an interest in Philip Shaddock, who is a leading guppy breeder. I found him on Facebook, and I find the extremely scientific way he approaches his work very interesting. He has a facebook fan group under the name Guppy Designer, and a website by the same name. He has published 2 books on Guppy genetics.
Here is a quote from a Facebook discussion on one of his pictures explaining the coloring of his guppy cross "It would have to be autosomal dominant, since outcrosses with my Full Platinums (more correctly called Full Gold Leucophores) show the saddel in the F1 generation. I assumed that my Full Gold Leucophores were both x and y linked saddle. But I suppose they could have been autosomal dominant. That would make it a rare type of mutation." - Guppy Designer
I think his knowledge of fish genetics could be very beneficial to all members of the club, especially those that breed live bearers.
Thank you for taking the time to consider my suggestion
