Posted April 3, 200817 yr okay so this is why I can not sleep now .... Dom x rec breeding ... outcome will be 100% Dom/ Rec .... But what if there are a few factors of the Dominated gene Yf, Opaline would they all be YF / rec ..... I have a Yf Colalt opaline Hen THIS WAS HER AS A BABY SHE IS MUCH DARKER NOW ( i think mauve has she isn't bright more dull) and a Colablt (bright) Rec pied ( could be clearwing or clear flight .... What will be the outcome and why????? Her parents are DAD mum His no idea Edited April 3, 200817 yr by Neat
April 3, 200817 yr okay so this is why I can not sleep now .... Dom x rec breeding ... outcome will be 100% Dom/ Rec .... But what if there are a few factors of the Dominated gene Not sure what you mean by here if you can explain it more. Yf, Opaline would they all be YF / rec ..... I have a Yf Colalt opaline Hen THIS WAS HER AS A BABY SHE IS MUCH DARKER NOW ( i think mauve has she isn't bright more dull) and a Colablt (bright) Rec pied ( could be clearwing or clear flight .... What will be the outcome and why????? Personally in this picture your hen looks violet not mauve but maybe it is the flash. The hen is carrying the opaline gene so she is going to give the opaline gene to all her male offspring but they will only be split because a male needs 2 opaline genes to express it visually. Now if you get any opaline hens that would mean that your r. pied is carrying the gene too (he would be split for it) and all the hens will show it visually because a hen needs only 1 opaline gene to express it visually. (if you want to know more why let me know). You will only have r. pieds if the hen is also carrying the r. pied gene (meaning he is split to this gene) but if he is not you will only have normals. You will only have blues since it is a recessive gene. Depending on how many dark factors each bird carries is going to determine the darkness of the blue. If the hen is a violet that brings in another added factor too. So if there is no r. pied gene in the hen you will have & the male is not carrying the opaline gene your basic outcomes can be 100 % normal hens blue 100% normal cocks split to opaline No the yellow face is another thing (Laughing out loud) if the white face is a true white face then you will have 50% yellow faces & 50% whites. Hope that helps
April 3, 200817 yr Elly is right, that hen looks violet cobalt. The mom was most likely a violet mauve. YF2 opaline cobalt violet hen x recessive pied cobalt cock = --50% of all chicks will be YF2 --all males will be normal split opaline and rec pied --all females will be normal split recessive pied For colors: 12.5% mauve 12.5% violet mauve 12.5% sky 12.5% violet sky (vibrant cobalt) 25% cobalt 25% violet cobalt (visual violet)
April 6, 200817 yr Don't forget that some of your "dominant" genes are actually semi-dominant. By this I mean they have different appearance in double and single factor. Examples: a double factor yellowfaced blue looks different to a single factor yellowfaced blue a double factor dominant pied looks different to a single factor dominant pied a double factor spangle looks different to a single factor spangle So your offspring may or may not inherit a semi-dominant factor from the parent if it is in the parent bird as a single factor only. Also, your yellowface cobalt opaline hen could be carrying recessive genes for other varieties you may not know about (other than sex-linked ofcourse - hens can't be split for sex-linked), your recessive pied squire could be carrying sex-linked recessive and other recessive genes too. Never can be exactly sure what you will get. (Hmm... a texas clearbody, fallow, recessive pied, clearwing... I wonder...) That's the fun! Example: I paired an olive green recessive pied squire (descendant from a normal olive hen and normal dark green squire) to a normal dark green hen (descendant from a normal dark green hen and a normal violet squire). I was expecting to get all normal/recessive pied offspring in various shades of green and blue series. I have produced from this pairing all sorts of fascinating permutations and combinations: normal cocks (blue and green series various shades and violet variations) yellowfaced blue normal cocks (assorted shades of cobalt, violet and mauve) normal hens (green and blue) opaline hens (green and blue) cinnamon hens (green and blue) cinnamon opaline hens (green and blue) texas clearbody hens in green and blue series (normal, opaline, cinnamon, cinnamon opaline, yellowfaced blue normal, yellowfaced cinnamon blue, yellowfaced opaline blue, yellowfaced cinnamon opaline blue variants of texas clearbody - various shades of blue and green) yellowfaced hens (normal, cinnamon, opaline, cinnamon opaline) Apparently my recessive pied squire is split for texas clearbody, opaline, cinnamon and is carrying a hidden yellowface gene too. Both the parent birds carry dark and violet factors and both are par blue. If your recessive pied is split for cinnamon or opaline, you might get these variants in hens, and you might get opaline cocks too since your hen is opaline, and half the babies will inherit the yellowface from the hen. Sometimes nature throws curly ones at you as well, example, I bred two opalines together and produced a normal - just weird, I am thinking there may be at least two different loci for making a bird look like an opaline, just like there are different types of pieds that are dominant (australian dominant, clearflight, dutch). Also, have paired a double factor spangle hen to an opaline cock and you would think that all the offspring would be spangles, but no, an ordinary opaline hen popped out. I have also just been given an interesting squire bird to experiment with that looks like a recessive pied, has one red eye and one dark eye, and has produced both dominant pied and recessive pied babies when paired to a normal/recessive pied hen - weird... mutations eh! Never can be 100% certain of what you will get. Although your hen looks to be a yellowface opaline, having a mother who is a dominant pied and a father who is a spangle - even though she seems not to have inherited either of these semi-dominant genes expressed in her phenotype, it wouldn't half surprise me if nature threw out a pied or a spangle, or a spangle pied from either her or her offspring somewhere down the line (or something completely different!). Unlikely, but we don't know exactly how the genes to produce the appearance of these varieties work and how they are inherited, whether a single gene on a chromosome, or a multiple complex. All kinds of theories. Lots of possibilities. Those varieties came from genetic mutation(s) somewhere in the first place. Keep your mind open to new possibilities. Edited April 6, 200817 yr by DrNat
