A little more about colour genetics... (Sheep Colours as it relates to my flock - Part 3)

There are other loci that are of interest in relation to colour genetics, but I'm not going to say much about them!

One that must be mentioned is the S-locus - the spotting genes!

How they work seems to be a little controversial, and I haven't had a lot of spotting in my flock, so can't comment much.
~ If it is dominant, I probably don't have it currently.
~ If it is incompletely dominant, then I may have it, hidden...
~ And if it is recessive, then I probably do have it, hidden!

 Triplet lambs born in my flock - two of which appear to have been spotty

One of the same lambs last lambing with her own twins

The moorit one of her twins is one of the two ram lambs that I used this year...

A few web-pages with more information, inc more about the A-locus alleles...
Some of these have photos of sheep with various genetics.
It must also be noted that some of these sites deal with specific breeds of sheep.
