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.

What are the examples for heterosis?

Having mixed breed dogs rather than pure breds.


What is good about crossing Simmental and Angus?

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.


Can you cross your Murray grey cows with a belted galloway bull?

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.


What bull can you use to your black brangus to get a black baldy?

You can use a Simmental (white-faced one) or a Hereford. Hereford over Brangus would probably give you the best in terms of heterosis.


What are the advantages of mixing a highland bull with another type of cow?

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.


What is the best cross shorthorn bull on hereford cow or hereford bull on a shorthorn cow?

Both will work just fine. Neither cross will have the desired heterosis like Hereford on Angus or Hereford on Charolais will.


What does the root word hetero mean?

heterosis, heterologous, heterodoxy, heteroousian, heterogenous, heterochromatic, hetero(P)thallic, heterokaryon


How can hybridization be used to produce plants with characteristics needed to increase food production?

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.


Would a shorthorn bull on beefmaster cows be a good cross?

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.


What is hybrid seed technology?

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.


Why commercial exploitation of heterosis is not feasible in wheat?

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.


What are sheep breeds used for meat products?

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.
