That's right what EAT BEEF said.
Red Bull Breeder":34b8unlv said:Very simply put if it ain"t red it crossbred. Jovid i think you figures are pretty close to right. Figure a 87% cow and a 92% bull see what you have. When you quit using fullbloods to keep your precentage up only way you can go is down.

I don't understand. 87% x 87% would yield 87% offspring. Just like 100% x 100% yields 100%, and 50% x 50% yields 50%.
You're still multiplying when you should be adding. 87% + (plus, i.e. added to) 87% divided by 2 still comes out to 87%Jovid":1fmglm2d said:ArmyDoc":1fmglm2d said:Red Bull Breeder":1fmglm2d said:When you keep breeding %87 to %87 it keeps going down over time.

Nope ....87% x 87% = 75.69%
100% x 100% = 100%

NCSU Maverick":3a2cba47 said:Not to add fuel to the fire, but I think Jovid's point is valid.
Although I don't understand where his math is coming from, I think his point is that after the F1 generation, you dont know what percentage you have.
NCSU Maverick":3a2cba47 said:When you cross two baldies, you are most likely to have to have a 50% angus 50% hereford but you could (correct me if i'm wrong), genetically, have anywhere from 100% angus genes to 100% hereford genes. Parentage wise, you have half the genes from the sire and half from the dam but breed wise you really dont know.
NCSU Maverick":3a2cba47 said:It looks to me like if you had two animals that you knew for a fact were each 94% gelbvieh then, when mated, their offsring would be a minimun of 88% gelbvieh but would most likely be 94%.

Red Bull Breeder":3nk71msf said:Your right the math is the same 87+92=179 179 divided by 2 is 89.5. It takes a while but somer or later you will run the precentage down unless you try not to.
haha, we usually breed the full cow (thats 100% cow). ive never seen anyone only breed 87% of a cow. BTW what was so wrong with bull? The first 2 pages didnt say to much only you needed thick skin to hear it.Alan":33zcs48g said:Ah man, just when I got the popcorn done and ready to enjoy a good bashing of another banned poster getting caught on a reappearance....

yea if my year of biology serves me right thats how it works. which traits get expressed depends on all that hetergenous/homogenous recesive/dominant stuff.
