Question on Lavender genetics...

[Krys109uk]

If your parent stock are all either blue or splash & each is carrying a lavender gene. In the region of 25% of the total offspring would be lavender. Also the offspring would be about 50-50 blue & splash.....no blacks. The 25% lavenders would also be either blue or splash at the same time as lavender & blue are completely separate genes, they are not alleles.

Your chart is missing part of the genes. Should be

Bl / bl

bl Bl/bl bl/bl

bl Bl/bl bl/bl

= 50/50


Oh gosh--you're going to make me work out a punnet square on two genes!

not exactly my strong point. How about we use the chicken calculator instead? http://home.hetnet.nl/~h.meijers69/kruising.html Black roo to blue hen, both split for lav? Select those choices then click on Calculate Crossing.

Yes, Henk, lavender and blue in the same silkie is getting quite common here.

Actually, the offspring who end up bl/bl lav/lav will be visibly lavender. Those who are Bl/bl lav/lav and Bl/Bl lav/lav will look more like the blue or splash than like lavender; however they will display a phenotype somewhere between the blue (or splash) and lavender phenotypes.

Dont need to work out a square for 2 genes...... lav is gonna be homozygous in your pen after a few generations if you breed correctly. All your birds will be lav/lav. then you will have some who are lav/lav bl/Bl, some lav/lav Bl/Bl, and some lav/ lav bl/bl. so you will have lav birds and be back to breeding for blue as normal.

See, I told you it had been a while. I couldn't make any sense of that chicken calculator.

Thanks!​

I tried to get it so that I could give you a link htat already had everything selected, but couldn't figure out how to do it. http://home.hetnet.nl/~h.meijers69/...,S:S/(S)&fgt=E:E/E,Bl:Bl/bl+,S:S/(S),Pg:Pg/Pg has most of it, but I couldn;t figure out how to add split lav (Lav/lav) and get the link to work correctly. (So you will have to go in and select the lavender genes as described below.)

First, realise that just about everything is listed in several languages: just keep looking until you see the English--although it's usually the 2nd

Basically you select each parent bird's variety, either by name or by selection the picture of the desired colour. So for the cock you will select black; for the hen you will select blue laced (as all US blues are laced, or at least supposed to be according to the standard). The pictures only show blue, but the list has blue laced.

Then you can alter any of the specific genes--such as if you know your bird is gold or silver, you can make those selections. If you selected blue from the pictures, go in and select PgPg MlMl and CoCo to change your blue to laced. For both birds you will want to select Lav/lav as they carry (are split to) lavender. Okay--now you have the genotype for your parent birds. It's likely not exact as silkies are usually e^b, but I don't know how to make a black e^b bird on the calculator. My incubator and yard show that my birds know how, though

So, once your parent birds are described, press the button at the bottom right that says Calculate Crossing. The results will show pictorially, with genetic name of the variety and list of genes. The first group shows genesets: the birds with exactly the sme gene combinations. Down below in the 2nd set it will show a more concise breakdown by phenotype.

Best remove the http:// part and let them select the hyperlinktext and paste into address field of browser.

I personally would not get birds from this person since they seem not to care about the proper breeding aspects of the birds.

You really should keep the lavender and lavender splits seperate from the BBS.
