PILE-O LAVAS & LAVA CINDERS !!

I purchased 2 Homo Cinder females from Carol a few years back, both bred this season, 1 clutch was a crap shoot with bad fertility and all the good eggs ended up dying. The other clutch is fine, I haven't sexed them all yet but of the ones I have it was a 3.2 so far. I will sex the rest tonight and post it.

It was Cinder X Cinder pairing.
 
Yes, we'd expect an equal sex ratio in a cinder x cinder pairing because the cinder allele isn't affecting the sex ratio of the clutch as a whole. I predict that if you breed a het cinder male to one of those cinder females from Carol, you will get both male and female cinders.

So is this correct?

WT= Wild Type

I didn't think I was going to post this when I was writing it out, or it would have been neater...

Yes Nanci. I was about to upload a similar chart but your handwriting is better than mine :)
 
So I am quite happy that a female peppermint is the foundation dam for my peppermint tessera project! Bred back to her son, I should get a 50:50 M/F mix.

My other two cinder projects- my targets will all be male. Unless there is crossover.
 
Yes. Given enough data, we could eventually calculate the probability of a crossover, although based on the results from Carol and Walter, the frequency is very low. I guess the moral of the story is that it seems prudent to start cinder projects with a female that is homozygous cinder.
 
So- since it appears that cinder is apparently sex-linked, I wonder if any other genes are?
 
I think the corn has 36 chromosomes and the Z and W are small, so the odds aren't high by any means, but it's something to keep in mind especially as new single gene mutants are discovered. Cinder is a newer mutation so I'm not surprised this is just coming to light. Imagine the headache involved with combos of sex-linked genes!

Good news for anyone hoping for a peppermint stripe male from squirrel and chipmunk, though.

The good news, I guess, is that so far all of the data we have seems to follow Duxor's hypothesis. As long as that continues to hold up, it might be a pain to work with, but at least we'll know what we are working with. Much better than just thinking you are getting really bad odds over and over and over.

I agree and......

.....This is what I thought the first year, but then the following not so much and then this year, GOTTA be something going on !!

Extremely interesting read. Cinder girls are going to be a hot item now. To bad I don't have any. Now I know why. lol
 
I had a feeling something was going on. My pairings that the target morph was hypo cinder, have yielded male hypo cinders and female hypos. Now that I really think about it the only female cinders I have hatched were from het cinder x het cinder pairings.
 
Jen, if you hatched female cinders from a het cinder x het cinder pairing, do you happen to know the genetics of the sire and dam that produced the het cinder female?
 
One pairing, The Dame was a miami het cinder I had from Carol H and The sire was a het cinder from Serpenco.
I'm going to have to look at my records and get back to this thread. I believe I have hatched 3 of them so far.
 
In the pairing that produced female cinders, were there any males produced as well? I wonder if the miami het cinder was the result of crossing a miami male to a cinder female. The resulting het cinder would be on the W chromosome, and this dame would produce females when mated to a het cinder male.
