Thanks for the information. what does autosomal dominant mean for this gene?
Same meaning for this gene as for any other gene:

Autosomal means it's not sex-linked.
Dominant means that if the bird only has one copy of the gene, you can see the trait. So a bird with one copy of the rumpless gene (dominant), and one copy of the gene for having a tail (recessive), will be rumpless.

its completely dominant as Rp/rp+ are as rumpless as Rp/Rp, most genes are either incompletely dominant or co-dominant

I thought that was the usual meaning of dominant--completely dominant, unless stated otherwise.

True, but its rarely mentioned in an informal setting like these forums and most people are not aware of the difference between incomplete, complete and co-dominance of some genes, for example dominant white is actually co-dominant
