Friends new yearling bull what ya think?

[KNERSIE]

So each parent contributes 50 percent and we breed the half herford half angus back to a herford we should have a whole herford??

You can never breed up to 100% if another breed was in the genepool.

I'll try one more time....

50%Hereford 50%Angus bred to 100%hHereford 0%Angus
= 1/2(50%Hereford 50%Angus) + 1/2(100%Hereford 0%Angus)
= 25%Hereford 25%Angus + 50%Hereford 0%Angus
=75%Hereford 25%Angus

 

[Red Bull Breeder]

We had all nice even numbers where did all the odd ones come from. If each parent contributes 50 percent you should have a whole herford. I no we don"t have a whole herford Knersie. But you would have a good start on a black herford.

Where did the angus part go?

Angus to hereford is 50:50 angus and hereford. Breed that 50:50 calf to a hereford and the resulting calf is 75% Hereford and 25% angus. Breed that calf to Hereford and the resulting calf is 87.5% Hereford and 12.5% angus, etc. , etc., etc.

 

[Angus Cowman]

after 15 breedings of goinr back with a 100% herf you would be back to a 99.998% hereford offspring

 

[Red Bull Breeder]

But go back just once with a half angus and what have you got??

It figures the one that wants to act like an idiot is from Arkansas.

That was uncalled for.

Thats alright FarmGirl10 i have seen the wind blow in Texas before its mostly hot air. I am pretty sure Knersie and Dun knows i have been yanking there chains a little. Old tater head just ain"t figured it out yet.

Ok. You got me. You've restored my faith in the Ar-Kansasians.

Don't be so up tight and have a little fun. If you get your feelings hurt on the internet you've all together different issues. I thought farm girls had thick skin and thighs. ;-)

 

[Red Bull Breeder]

That is Arkansaw. We can't help the fact that the fellar doing the offical spelling of the states name way back when didn't get it right.

Must have been the same guy that screwed up the spelling of Missoura

 

[Red Bull Breeder]

I am sure it was Dun.

I think you could theoretically breed hereford X angus to a second hereford X angus and end up with 100% hereford, but the gene at each locus would have to be from the hereford side and as there are millions of genes, the likelihood of that happening is essentially zero. I don't really want to add fuel to this conversation, but if you sequenced every gene, I think it is almost as unlikely that the offspring would be exactly 50% hereford and 50% angus.

Technically yes, but until someone comes up with a better model we'll have to assume this one, like Einstein's relativity theory, it can't yet be proved, but it hasn't been proved wrong either.

I think this is what I was getting at about 3 pages back. Obviously each parent provides half the genes. So adding the total breed percentages of each parent and dividing by 2 gives you the most likely breed makeup of the offspring but you could not know the exact makeup.


If a 50/50 baldy bull put all his genes in a bucket, then I reach in and pull out half the genes from the bucket who's to say what combination of angus and hereford genes I get? I would be most likely to pull out 50% angus and 50% hereford to pass onto the calf but it could be 65%/35% who knows?

Does this make any sense or am I way left of center?

Well, I still don't think that's right, but now I'm having second thoughts. I've sent an email about this to a beef specialist at the U of Illinois. Hopefully he will respond and if/when he does, I'll pass it on. Don't really care if I'm right or wrong but now I just HAVE to know. ;-)

What do you all think about my new friends new yearling bull?

Friend has him in with 5 heifers right now.
Breed Gelbvieh

Any and all comments welcome. My friend tim has thick skin.

Actually you are correct but in the cattle industry it is assumed that all the genes remain at the same ratios.

Here is the email I sent last night and the answer. Take it as you will.

Van-

All science says the calf is half Hereford half Angus.
