Cardigan corgi coat color genetics is really fracking complicated. I was told, I think, that if you cross a merle and a tricolor you get ALL the colors. I THINK. But I don’t really know, or understand.
Can anyone shed some light on Cardigan coat color genetics? What is the most common cross? Why?
Brindle x Brindle = All variations of black, brindle and maybe a tan?
I know Merle x Merle = possible lethal or undesirable “forbidden” cross even if it will give you all merles, because double merle means you can get deafness (white ears).
For your end of year corgi examination, please submit in detail a summation of possible crosses and genetics. Pictures of potential crosses = automatic honors in
corginomics correction, corginetics. ;)

- shineagaingold said: pretty much any combo can create all the colors, but for the most part, they breed true. However, because blue merle’s are more rare and have a smaller gene pool, its an unspoken rule that two blue merle’s don’t breed together. but if one of the parents is blue, you’ll…
- bellethebadwolf said: In terms of genetics in general, you have more possibilities than are present in the parents. There are at least two alleles per parent per gene, but only one is expressed, so there are “hidden” ones that can be passed to the child and expressed :)
