Question: Number of Chromosomes in different Pythons

Hi :)

Im sure you know much more than i do, so what are the chromosome counts for different pythons? and sources would be nice. i heared somewhere that for ball pythons its just 17, but i have no source. And i just read online that the corn snake has 74, again, no source given.

Its one of these things that never change once you properly figure it out. I somehow doubt it, but if it is true that the bally python has only 17 chromosome pairs, imagine the impact that would have on morph genetics.

Anyway, who can help? Who has sources? And in the unlikely case that nothing comes up... How expensive would the test be per species and who can do it? (Im not into that, but for these that are into hybrids between different python species... listen up.)

1. BLBC discussion on chromosome count (with a link or two sprinkled in...that may or may not be in German?)

2. Very abrupt Fauna thread addressing the same question

3. Not specifically chromosomes, but if you were not already aware, this is an interesting read on ZW Sex-linked mutations

thanks a lot, i would never have found these threads from 2010 or 2011.

When i searched i basically got flooded with stuff about the programming language python, which to make things worse appears to be frequently used in bioinformatics.

so its 18 chromosome pairs, 36 chromosomes in total, for ball pythons.

i guess when it comes to discovering that two genes sit on the same chromosome, we will get a lot more of that in the future.
