gentics qustion HLP DRAGONS

Postby genetics » Sun Mar 04, 2012 4:43 am

a male dragon that has flameless phenotype is crossed with a true breeding female that shows ragged wing phenotype. The F1 males are all flameless with half of them also having ragged wings and the females are all normal(wild-type) for flame but half of them having ragged wings.
I cant seem to determine what these look like in allelic notations and the below is what I think
For the F1 i think that the males: 1/2 flameless ,normal wings and 1/2 flameless , ragged wings
female: 1/2 flame, normal wings and 1/2 flame, ragged wings
Also the parents(P) i'm guessing are for male dragon flameless phenotype, normal phenotype and for female dragon ragged wing phenotype, flame phenotype

This raises the question of whether a good adaptation has a greater possibility of being dominant than a bad one. Obviously flame is better than no flame, and ragged wings are a definitely faulty gene. You are hampered by the fact that you can't know which strains are dominant unless you look more closely at the ancestry. Myself I wouldn't breed from any female with such a bad genetic defect.

You could decide that F is for flame and f for flameless, and W is for normal wings, and w for the ragged ones.

Then you try to figure out if any of the phenotype is sex-linked or not. Your description of the parents appears correct

I dont think its sex linked i rhink it may be autosmaul would the parents be WwFf cause i dont know XY for male and YY for female would work since there are 4 phenitypes and the Y phenotype doesnt have an allele im really lost cant determine what the parents would look like in allelic form

All female F1 have flame, all the male F1 are flameless. You write, "I dont think its sex linked". Why?

Okay your right so clearly the flame/flameless phenotype are sex linked through the zw or xy
System. Also for the ragged/normal they autosomal since
Equal ratios are observed throughout their gametes so like rr for purebreeding female and Rr for male parent.btw r=normal R=ragged wings

As per your description all the females would be with flame and half of them would be normal winged and the other half would be with ragged wings. But all the male would be flameless.
It looks like your cross is reasonable i.e it seems to be sex linked...
