I'm just an amateur. There is a huge amount of information available but it does help to have an understanding of the basics in order to interpret it 🙂
Thank you. It's pretty easy to understand if you just take it a step at a time. And I have kept it simple - once you consider multiple genes interacting it can get too complicated for me 🙂
@@chickensinmygarden I tried reading a quite theoretical book about this subject and even though I have a basic understanding of genetics (from school) I always had problems understanding them. I think you explain it very well, thank you for that. :-)
Thank you. I have subscribers from all around the world so I try to make videos that are useful for everyone but with a New Zealand perspective - there aren't many NZ video channels.
The genetics of Laced Brahma chickens is exactly the same as for Laced Wyandottes. So for buff-laced, you breed buff-laced with gold-laced or with buff-laced. For blue-laced you breed - blue-laced with blue-laced - or blue-laced with gold-laced - or gold-laced with any blue chicken (blue, not lavender).
@@chickensinmygarden I do find genetics in practice complicated. I have with a lot of pleading obtained six Partridge Chantecler hens and one rooster. They are nice birds, the rooster is very good. I am happy to get them. But you have to work with what you got, and two of the hens do not have very good penciling. It gets more complicated, the roosters have a "wild type", (in general mahogany) feather pattern and do not show penciling, while the hens show the penciling for better or worse. So my dilemma is I do not know if my rooster is Pg/Pg, or Pg/pg+ or pg+/pg+. I have to make the assumption that Pg is autosomal, but hides due to other influences in the males. I want to avoid as much as possible breeding culls, I know it can't be helped, but I hope with a basic knowledge of genetics, I can avoid some pitfalls. I am leaning towards breeding my "proper" hens in one pen, and have a separate pen for the two hens that have imperfect penciling and bred them later in the spring. The genetic pool for this breed is said to be small, they are very hard to get, so I feel I should try with the "imperfect penciled" birds. My F1 birds will likely be OK, I will have to see about the F2 generation. In any case, thank you so much for your great instructional videos!
I loved your videos on Chicken genetics! I dont know if I missed it, but did you happen to cover recessive white traits? Specifically, I found a forum where they had discussed recessive white inhibiting mottled colors and markings. Is this the case?
No I didn't cover recessive white (the little c gene). Homozygous little c interacts in complex/subtle ways with other genes, for example it's well known to depress growth rate in chicks. So it's not unlikely that it would interact with genes for feather patterns, but I'm not aware of it.
I'm sorry about the delay in responding to your question - I've been wondering how best to help. There is not a book that I could recommend - I have gained my knowledge from many different sources, many of which were actually about human genetics rather than poultry genetics. I have tried to give a thorough grounding in the basics in my series of genetics videos, so that if you understand all of them, you should be well placed to understand more academic articles. In addition, I might point you to some internet resources which I have found useful: www.backyardchickens.com/threadloom/search?query=genetics&tab=620 edelras.nl/chickengenetics/ poultry.extension.org/articles/poultry-anatomy/poultry-genetics-an-introduction/ www.thepoultrysite.com/genetics-breeding And of course the genetics calculator site that I gave the link to in the description of my first genetics video: kippenjungle.nl/chickencalculator.html I hope those are helpful. I often start by doing an internet search for whatever topic I'm interested in, and noting the source or authority of the search results to determine which are worth reading. Good luck :-)
I have enjoyed your videos very much. I love genetics for color and pattern. I have come to realize that one of my favorites is Wheaten. I just love pastel cream colored hens like Salmon Faverolles. Could you do a video if you have time of how Wheaten works? I have a black copper marans rooster and soon will have a wheaten marans hen. But worry how that cross will go. Was not able to get a wheaten rooster. Plus the black one has been named already which means he's loved so I'm stuck with him. I also have a wheaten ameraucana rooster. With him I'm hoping to introduce blue gene for eggs into my faverolles. I know they won't be faverolles anymore but would love a lovely faverolle girl that lays blue eggs. I also have a blue favaucana hen that lays light green eggs. I'm guessing she's F1 because of that. So with my black copper rooster I think her daughters might be darker green eggers which would be wonderful. OH there's another fun topic. Egg genetics.
The eggshell colour is actually quite straightforward. There are two separate things going on. The blue colour is from a single dominant gene. If it's present, then blue cyanocobalamin is incorporated right into the shell material. It's not sex linked. So if your rooster carries the gene for blue-shelled eggs, there's a good chance that his daughters will too. The other thing that's going on is the brown colour on the egg shell, which is applied ON to the egg shell right before it's laid. This is not a single gene but several genes working together, so you can get a variety of brown colours from buff to dark chocolate, even slightly pinky shades etc. The thing about these is that although there are many of them, they are dominant. Only if the hen has NONE of them will her eggs be pure white. A hen with NO genes for brown eggs but with the gene for blue, will lay blue-shelled eggs. A hen with the gene for blue eggs who also has some genes for brown will lay eggs that look some shade of green - anywhere from light teal through to deep khaki depending on what brown-shell genes she has. You can guess what that might look like if you know how deep a brown colour her mother's eggs are. Oh, and the blue-shelled egg gene is carried on a chromosome close to the genes for comb shape. So by looking at the comb shape you can guess which chicks will lay blue/green eggs without waiting for them to grow up.
Generally the approach is to find a breed with similar body conformation and mate it with you OEG. Then mate the offspring back to OEG for several generations, each time selecting the best of the hybrids, to remove all the other non-OEG features. It takes many generations of careful breeding and strict culling to introduce a new colour into a breed. It also helps to have some understanding of the genes of both breeds you are working with - check them out on the Kippenjungle site. Laced colours already exist in OEG bantams so why not start with them?
I have two splash marans, they are very pretty. dilution genes in horses are white too, so if you want a palomino color dont use a palomino use a cremello, is actually a diluted red, with a chestnut color (use a horse wiht clean, clear red)if you want a buckskin use a ivory white horse onto a bay.
Do you mean 'why don't they breed true? It's because only heterozygous birds look blue, I.e. it takes one B gene and one b gene to look blue. And the blue parents can pass either B or b to their offspring, which can therefore be black, blue or splash. Or maybe my diction wasn't very clear and you thought I said 'through ' 🙂
@@chickensinmygarden thanks for the explanation.what is the gene for the blue laced red wyodottes chickens? And are there ways to determine the exact genotypes of a particular breed?
The gene that causes the blue lacing is simply the blue gene (b). It affects only the feather colour that would normally be black, so has no effect on the red ground colour of the feathers. A good resource for assessing the genotype of chickens is the Kippenjungle chicken calculator. kippenjungle.nl/chickencalculator.html But of course it's only an estimate based on the phenotype. The only way to be sure it by knowing the parent birds or breeding and observing the offspring.
I have been enjoying this. For me it's a refersher. I used to breed cockatiels. I was really into the white faces and had my line of quad mutations. They were sexlinked so I could guarantee the sex of the babies. But it's been years since I dabbled in genetics until now that I ended up with an accidental rooster. At first I thought it was terrible I had a rooster but now there's so much fun to be had. I have a blue splash marans hen. She's pretty but I noticed the "dirty" look on her head and hackles. I really thought she was dirty but now I know better. I definitely don't' like that. But what surprised me was that in all her pretty feathers I found on lone red feather buried in her rump. I didn't know how it was possible. But now I see blue which is dilute black is a different gene than red which is the pheomelanin. So I guess it's possible to have that one accidental feather somehow? I used to breed budgies too and my fave mutation was the yellow and white lacewing.
Yes I find genetics fascinating too. But of course unless you are dealing with very pure lines that you absolutely know the traits of and only vary a few at a time it's not really as simple as it sounds, so there's often a surprise 🙂
