Heterosis is a term used in genetics and selective breeding. The term heterosis, also known as hybrid vigor or outbreeding enhancement, describes the increased strength of different characteristics in hybrids; the possibility to obtain a genetically superior individual by combining the virtues of its parents.

Hybrid vigor, also known as heterosis, is the phenomenon where the offspring of two genetically different parents exhibit traits that are superior to those of both parents. This can result in increased growth, fertility, and overall health in the hybrid offspring compared to the purebred parents.
This is solved by simple gentics... some of the plants gain weaker genes while others gain stronger (dominant) genes The Hybrid can gain the stronger elements from both of parent plants making it have the best of the two (usually done in labs with geneitcally modifided foods to gain a super plant) this 'superplant' or hybrid plant can then be used to create more hybrid plants.
Having mixed breed dogs rather than pure breds.
Hybrid vigour or Heterosis. Calves with heterosis often excel at the feedlot in terms of weight gain and carcass quality than other calves do if they're purebred Simmental or purebred Angus. This is because they have the genetic qualities of either breed to make one superior calf.
Yes, since this will really put the emphasis on heterosis for MG-Galloway X calves. Belted Galloways are relatively the same size as MG's are, so the calves will come out nice and small, but VERY growthy. Heterosis, by the way, is achieved by breeding one breed of bovine with an unrelated different breed of bovine to get a calf that is superior (genotypically and phenotypically) to either of its parents.
You can use a Simmental (white-faced one) or a Hereford. Hereford over Brangus would probably give you the best in terms of heterosis.
Heterosis. The calves produced from this cross (and hopefully it's a good cross!) will express genes from both parents, but in a more superior way.
Both will work just fine. Neither cross will have the desired heterosis like Hereford on Angus or Hereford on Charolais will.

because the behr cannot respond quick Edited answer: During hybridization additive gene action from the two parents result in heterosis which ultimately increases food production in crop plants.
Yes. Though you won't get the heterosis like if you crossed those Beefmasters over Limousin or Charolais, you're still going to end up getting good calves, provided you make the right choice with your bull.
In hybrid seed production, the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis. To produce hybrid seed, elite inbredvarieties are crossed with well-documented and consistent phenotypes (such as yield) and the resulting hybrid seed is collected.
For a plant to express heterosis, it must be a hybrid, or the offspring of two separate and genetically distinct parents. Producing corn hybrids, for example, is reasonably easy, since all that must be done to produce the seed is to plant both parents throughout the field, then remove all the tassels, or pollen-producing parts, of all the designated "female" plants. By then harvesting only the "female" plants, only true hybrid seed will be the product. Wheat, though, is a very different matter, since the pollen-producing parts are on the same part of the plant with the ovaries. While physical removal of the pollen can be accomplished, it is extremely difficult, especially in any large quantity. It might be possible to produce "male-sterile" parents, such as are used in hybrid onion and carrot seed production, but the economic value of the wheat would not justify such expense.
i dont no The are many breeds of sheep developed primarily for meat production. Nearly every country has their own landrace breeds for this purpose. In the USA we often use crossbred animals for meat production due to heterosis.( Pork is also often produced from hybrids.) If you are looking for a pure breed for meat production the Tunis is tasty and efficient.
