| ORIGINAL BOOK REVIEW by Dr. Rainer R. Erhardt "Well, there is help on the horizon and anyone seriously interested in color genetics should take a look at Linda Rubin's book: COCKATIEL GENETICS MADE EASY! Though this book is primarily directed to breeders of cockatiel mutations, there is enough information in this little volume to teach anyone the secrets of dealing with recessive, sex-linked, and dominant mutations..."

| LUTINO CINNAMONS Copyright © 2003 LINDA S. RUBIN CF Genetics Consultant/Panel Judge www.CockatielsPlusParrots.com Selected Q&A's "From My Mailbox" QUESTION I have heard that when you breed a Lutino cockatiel to a Cinnamon cockatiel you can get "dirty" Lutinos. Is this true? Also, does this theory apply to just Cinnamons and Lutinos, or Cinnamons and Lutinos that are also Pearl? Just wondering. Thanks. Tristan ANSWER Hi Tristan, First, I must point out that breeding a Lutino cockatiel to a Cinnamon cockatiel will not produce the cross mutation Lutino Cinnamon unless each parent has the correct genotype (i.e., all the necessary color genes in its genetic makeup). Because both the Lutino mutation and the Cinnamon mutation are sex-linked, the following will hold true: 1. A sex-linked sire will produce visual sex-linked daughters and split (non-visual) sex-linked sons 2. A sex-linked dam will produce split sex-linked sons and non-linked daughters (non-linked daughters neither show nor carry the mutation). We would have to know the exact pedigree and which mutations each parent showed or carried in order to accurately predict or chart the offspring expected. Now, on to what I believe is at the heart of your question. In the short answer, yes, it is true that in some (but not all) bloodlines, there is a possibility that some Lutino Cinnamons will "bleed through." Bleeding through, in essence, means that the Lutino gene is unable to totally suppress the Cinnamon gene. Therefore, a weak Cinnamon cast to the feathers - usually the back, flight and tail feathers – can be seen. This break-through of a cinnamon tinting, according to current show classifications, is not desirable and therefore such birds are penalized on the show bench. To answer the second part of your question, yes, Lutino Cinnamon Pearls can also show a cinnamon tint to their plumage. Some aviculturists find it quite attractive as the cast accents the pearl lacings in this triple mutation. However, again, at this point in time, any “break-through” of cinnamon color would be considered a fault and therefore would be penalized on the show bench.
