Pedigree Cattle Names - Polled

[Crex]

If an animal has (P) after its name, does that mean it is homozygous polled?

Thanks

Don’t know if all breeds are the same but in sims P after the bulls name would mean the bull is heterozygous.
PP would mean homozygous.

 

[Gulli]

No, can be either with herefords (don't know about other breeds)
But also horned and dehorned will be on the pedigree.

 

[Crex]

This would be for shorthorns.

I think so yes.
But not neccesarily a full poll, so you could still get horns.

I wouldn't have said it would guarantee it. The P could just mean it was born without horns, and registered before any tests were done. You would need the calf genotyping to be able to say if it was homozygous or not. The genotype result would be either Pp = heterozygous, PP = homozygous, or pp = no polled gene.

For shorthorns the P just means it's polled, not whether it's homozygous or not .

For shorthorns the P just means it's polled, not whether it's homozygous or not .

Or the breeder thought it was polled when it was registered
