sheep colour genetics
« on: December 20, 2011, 01:20:55 pm »
Having kept coloured shetlands for years I have only just bothered to find out about colour genetics. I had no idea it was so simple or so fasinating. If I had kept records of the different lambs each ewe has had I would by now know exactly what genes they all had. As it is I will need to start the process now.
My Moorit ram is easy to work out because brown and unmarked are both recessive so I know he has homozgotes (matching pairs of the brown gene and the unmarked gene. I also know that he has a hetrazygote (not matching pair) of spotty and unspotty. Thats because he has produced spotty lambs and because spotty is recessive a lamb needs a homozygote of spotty genes (one from each parent) to be spotty.
I'm starting to get obsessed with this!

I just joined the Yahoo sheep colour genetics discussion group and having asked a question and got several answers I am going to need to retract my comment about the subject being "simple".

I don't know too much about sheep colour genetics but have studied and taught equine genetics and that is fascinating but can be a hugely complex topic. It is addictive when you start mapping though and it just draws you further and further into the possibilities of the resultant progeny. Good luck with it, I'm sure you will get more and more fascinated the more you look into it  ;D
