**KAZ** 0 Report post Posted February 5, 2009 THE DARK FACTOR by Keith Leedham taken from April 1992 Budgerigar World An excellent subject for discussion is the pairing of two dark factor birds. Before we do this let us restate what we know about colors. The two basic colors are Green and Blue plus their dilutes. Yellow and White have three shades. Light Green, Skvblue, Light Yellow and Skyblue White have no dark factor. Dark Green, Cobalt, Dark Yellow and Cobalt White carry one dark factor whilst Olive Green, Mauve, Olive Yellow and Mauve White carry two dark factors. The above colors can be modified by the Grey or Violet genes, although the three shades still exist within the modified colors. A practical consideration is that from experience and observation the continual pairing, generation after generation, of two dark factor birds' results in the reduction in size of the resulting program. All budgies have a level of "dark factor" ranging from no dark factor, one dark factor, or two dark factors. Wild budgies have no dark factor. Dark factor basically darkens the blue in the body feathers. (In budgies totally lacking normally colored feathers, such as albinos and lutinos, the budgie's dark factor will be present but unknown). A green (yellow-based) budgie with no dark factor will be the original very bright green; this variety is called "green" or "light green." One dark factor will result in a darker green; this variety is called "dark green." Two dark factors will result in a deep olive drab green color; this variety is called "olive." A blue (white-based) budgie with no dark factor will be the original bright sky blue; this variety is called "sky blue." One dark factor will result in a slightly darker blue; this variety is called "cobalt." Two dark factors will result in a deep grey bluish color (more grey than blue); this variety is called "mauve." Within each level of dark factor is room for some variation in darkness. One sky blue may look a little darker than another sky blue and one olive budgie may look a little lighter than another olive budgie. But usually there is no mistaking which dark factor category a budgie falls into, and the pictures below can be used as a guide. Basic Genetics: Dark factor - semi-dominant Normal - recessive There are only two alleles that determine the darkness of a budgies body color: the normal gene and the dark factor gene. The dark factor gene is semi-dominant to the recessive normal gene. This means that a budgie that has one dark factor and one normal gene looks different from a budgie that has two dark factor genes. A skyblue has no dark factor, a cobalt has 1 dark factor and a mauve has 2 dark factors. A violet is a blue with 1 dark factor (cobalt) plus the factor for violet. Table of expectations The following table shows the theoretical expectations from various pairings. KEY: Lt=No Dark Factor, D=One Dark Factor, DD=Two Dark Factors Pairings Expectations Lt x Lt =100% Lt Lt x D =50% Lt, 50% D D x D =25% Lt, 50% D, 25% DD Lt x DD 100% D D x DD =50% D, 50% DD DD x DD =100% DD The offspring in this table can be of either sex irrespective of the dark factor genes carried by either parent. It is also noticeable that in general the progeny carrying two dark factors are smaller than the birds carrying none. Of course there are always exceptions to this type of observation. Many fanciers may well recall various exceptional birds carrying either one or two dark factors. If the aim is to produce birds that have a single dark factor, I have found it to be more beneficial to pair a single dark factor bird with a bird carrying no dark factor. This will produce a theoretical 50% of the progeny carrying the single dark factor, and normally without reducing the overall size of the bird. Share this post Link to post Share on other sites

RIPbudgies 0 Report post Posted October 28, 2010 Did you know a cinnamon fallow is a dead ringer for a lacewing Yup, currently got two of them. If you look very carefully you can tell by the tail. Share this post Link to post Share on other sites

nubbly5 0 Report post Posted October 28, 2010 And by the rump but you REALLY have to know what you are looking for(just VERY slightly coloured compared to lacewing but you wouldn't see that in opalines)! And yep I've bred 2 of them. How ARE those cin fallows going RIP? Also overheard one fellow at a club meeting saying I got these lacewings from my fallows and I've not had a lacewing near the place ever........ I asked if they were hens, yep! was the answer. We they are likely to be cin fallows then.................. Share this post Link to post Share on other sites

GenericBlue 0 Report post Posted December 23, 2011 YEP ALL YOU COULD EVER NEED TO KNOW ABOUT YF BIRDS AND GENETICS BREEDING THEM thanks to rip i had these i asked her last year for them as when i foirst breed pets rip had a web sight that i learnt all i know from genetic wize i did not know it was heres till last year but was closed down due to the people which sucked was best one i ever ever seen so ........... eat your heart out happy reading GREEN, YELLOWFACE, BLUE MATING TABLE This table is for Green, Blue and the various Yellowface group which form a Multiple allelic Yellowface series. There are three recognised Yellowface varieties at this time: Goldenface, Yellowface Mutant 2 & Yellowface Mutant 1. All various Yellowface mutants are recessive to Green, but are dominant to Blue. Since the Yellowface varieties have for so long been referred to as Single or Double Factor birds this trend will continue in this table. The word Yellowface in this table will be followed by M1 or M2 to designate which Yellowface Mutant is concerned. For matings of each of the Yellowface Mutants as a separate group refer to the Dominant Mating Table.
