The genetics calculator can be found at

A backup is at

=======================================

Hi,

I'm working on a genetics calculator inspired by Tadkerson's and Kazjap's versions.

While writing the code for a color deducing program I was wondering how some rare genes interact

What would the fenotype be of these:
Id/Is (dun/smokey)
I/? lav/lav
choc/choc Bl/bl+ or Bl/Bl

Any help appreciated wink

Pretty sure that the middle one would be white because dominant white suppresses all eumelanin production (apart from a bit of leakage).
No idea how the other two would turn out.

Good Morning Henk,

wait!;-) Tadkerson has a genetics calculator, also? Please, say where I can find it? I know Kazjap's already (both versions) but not Tadkerson's, hence my question. Sorry to be unable to help you but rather add another question!

I wish you success with your calculator and hope you´ll keep us all updated when it´s finished!

Best greetings,

Joachim

Id/Is (dun/smokey)-Never seen any order of dominance on these, likely to be a greyish brown of varing shades.
I/? lav/lav- I agree with Hen-Gen.
choc/choc Bl/bl+ - again likely to be a greyish brown of varing shades.

choc/choc Bl/Bl - Possibly a mainly white bird with choc splashes or a very pale milk chocolate.

As Is are only in a few hands in the US, and choc likewise in the UK we are not likely to see any test matings.

OK,
Thanks so far.

I uploaded a first version of my calculator in readable self written javascript code:

Careful! See the warning on the screen.
People with old gear think twice.
Keep it simple (not too much different loci).
It needs a lot more work and pictures.

Let me know what you think.

Brilliant work. Could play with that for hours! smile
One question? Do you have the chocolate allele down as a sex linked recessive? Some sources have it as an autosomal recessive?

Yes, I have it as sex linked recessive.
See also the dominant white locus allele Id = dun.
I saw that choc hasn't got any effect. Bug.
Should be fixed now.

Ii lav lav is very interesting on wheaten and it certainly isn't white. the rooster has very shadowy grey lacing.well mine do anyhow.

New version of the calculator:

http://home.hetnet.nl/~h.meijers69/kruising.html

You can hide the coarse results (genotypes) to see a summary of the crossing: only colors and percentages.
Pictures in the result are clickable. Not that they are suitable for that, but sometimes the patterns were hard to see.
