No such cow exists! I don't know how or why you would do this, unless it's for some sort of scientific experiment you are doing to compare different breeds with Herefords.
No. A Hereford cow will only give birth to a Hereford-Limousin cross calf if bred to a Limousin bull. Only a Limousin cow can give birth to a Limousin calf--IF she's bred to a Limousin bull. Just like a Hereford cow can only give birth to a Hereford calf if bred to a Hereford bull. Otherwise, she too (referring to the Limousin cow) can give birth to Hereford-Limousin-cross calf if bred to a Hereford bull.
On farms and ranches that raise and breed Hereford cattle.
Both will work just fine. Neither cross will have the desired heterosis like Hereford on Angus or Hereford on Charolais will.
Genetics. The genes in the momma cow combine with the genes from the calf's sire to create a calf with either the same colouration of the cow or not. What breed the calf's sire matters to. For instance, a Hereford sire bred to an Angus cow results in a black-baldy calf. Or, an Angus cow that has a recessive gene for Red colour and is bred to either a Red Angus bull or a Black Angus bull also with a heterozygous gene for the red gene can most likely produce a red calf. And the examples go on.
Friesians are black and white and produce lots of milk Herefords are brown, much furrier and are bred for meat
Depends on the cow. Some can go over $1500; others could be more, if they're registered, a 3-in-1, or less if they're open or short-bred.
An Angus or Galloway cow would be, yes, but not a Jersey, Simmental or Hereford cow.
The genes.
Whoever told you that the Hereford breed is a dual purpose breed is a numb-nut with his/her head stuck in the clouds. Herefords are and were solely bred for their meat, however docility was bred into these cows because of the people that originally bred and created them.
Hereford is a pure breed, and the origin of the colour pattern of the Hereford breed is pretty much unknown. So you can't find two breeds to cross to find Hereford, unless you can find a Hereford cow and a Hereford bull and "find" a Hereford calf!
To produce calves that are sold for beef.
Hereford or a Highlander
