Hello Fellow Pit Fans and Breeders,
I am looking to start a sperm competition/multiple insemination research project with my students in the next few years and need some basic genetics information. I am trying to figure out which color morphs in bull snakes are known to exhibit simple Mendelian inheritance -- recessiveness, codominance, epistasis, etc. I would appreciate any insight you’d be willing to impart. Online or off, mrand@carleton.edu
My goal is to be able to identify each individual offspring of three different males, each homozygous dominant for a single color trait, while homozygous recessive for the other two. Obviously the female needs to homozygous recessive for all three traits.
Here’s what I’m guessing is going on:
Amelanistic (=albino) - recessive allele
Anerythristic (= whitesided) - recessive allele
Axanthic - recessive allele
Hypomelanistic – is this a true recessive allele or a local variation that is a multigenic trait like the red bulls?
Double Recessives:
Amel X Axanth = Blizzard
Amel X Hypo = ?
Amel X Anery = Snow
Axanth X Hypo = ?
Axanth X Anery = Charcoal
Hypo X Anery = Ghost
Patternless – a recessive allele that is linked to the amelanistic locus or is this one of the missing double recessive traits?
HELP!
What is wrong here and what is missing?
Thanks in advance,
Matt
