Explain how a horse breeder might use selective breeding to produce horses that have golden coats?

There are two main golden coat producing genes, Cr (cream) and Ch (Champagne).
Both are dominant dilution genes.
Heterozygous Cream horses (Crcree) that are palomino colored will produce a palomino 50% of the time when bred to chestnut mares...bred to a palomino
mare the breeding will produce 25% cremellos 50% palominos and 25% chestnuts.
The use of a Homozygous for Cream stallion (CrCr)/a cremello will produce
100% palomino foals from breedings with chestnut mares.
The disadvantages of using the cream gene to produce gold foals is that the
homozygous individuals are not gold colored. This means that the color cannot
be designed to breed true in subsequent generations.
The advantage is that homozygous individuals are identifiable without genetic testing.
-----
A gold champagne stallion who is heterozygous for champagne Chchee will produce 50% gold champagne foals when bred to chestnut mares.
A homozygous gold champagne stallion will produce 100% gold champagne foals from chestnut mares.
The advantage to champagne is that a homozygous gold stallion or mare is gold colored with hazel eyes as the presence of two champagne alleles does not increase the level of dilution. This means that, over time, a breed could be
developed that is consistently gold colored 100% of the time.
There is a genetic test for champagne homozygousity,
If the only goal is to produce gold colored horses consistently the champagne
allele could be true breeding in as few as 2 generations using 2 homozygous
gold champagne stallions and as many gold champagne mares as could be
found to cross on them. Using this breeding format 50% of the foals produced would be homozygous gold champagne...culling the heterozygotes from the breeding program and back crossing them on the stallion who is not their sire would produce an F2 generation that was 100% true breeding gold champagne.
A search for additional homozygous gold champagne horses that could be
added to the breeding program to add genetic diversity could occur over time.
All this being said...breeding exclusively for color without regard for temperament, conformation or athletic ability is an error in judgement,

What did this selective breeding do to the level of genetic variation in domesticated beef cattle?
It has given producers cattle that are meatier for beef and that produce more milk for dairy. In selective breeding you are able to choose the genetics that best fit the cow, say she has strong conformation but low milk quantity, so you would choose a bull that is strong in milk quantity.
2rd question to your home workscientists are using zebras to try to produce quaggas by selective breeding you need to describe the steps in this selective breeding process plez help?

What term is used to describe the deliberae mating of two different breeds of animals to produce offspring with particular characteristics?
This is most commonly known as "selective breeding". It is also called "artificial selection" in an evolution sense.
What selective breeding technique has been used to breed purebred racehorses?
It's very important. Thoroughbred racing is a billion dollar industry so the breeding programs are vital to get the fastest horses possible. Bloodlines are studied so the resulting foal has the best genes for speed and the ability to run distances.
Can dogs and wolves interbreed to produce fertile offspring?
yes the can you should try it I am an experienced breeder. it is fun.
Varieties of purebred dogs are maintained is?
They are maintained by reputable breeder's who love a certain breed and produce high quality stock from good blood lines.
How has selective breeding helped in dairy farms in the United States?
By using selective breeding the farmers can get bedder produce out of the offspring of the animals.
When breeders produce changes in a species on purpose they are using what?
selective breeding
What is the crossing of plants and animals to produce specific traits in the offspring?
It is called cross-breeding, selective breeding or hybridization.
What dose selective breeding produce?
it give out hybrid offspring of desired quality.
The practice of breeding dogs to produce offspring with specific traits is an example of?
natural selecion
How is cross breeding different from selective breeding?
Cross breeding is simply taking two breeds of animals and mating them together (Such as a Charolais crossed with a Hereford). Where selective breeding is selecting the what two animals you want bred together to produce a better animal.
Do people have used selective breeding to produce many different dog breeds?
yes
What are the similarities and differences between Natural Selection and Selective Breeding?
The similarity between natural selection and selective breeding is that they both produce changes in plants and animals.
What is selective breeding?
Selective breeding is the process in which two animals from the same species reproduce due to useful characteristics. Two animals with a certain type of characteristic are bred together to produce offspring. Then the offspring with the most useful characteristic breeds with another offspring to produce more offspring. This process continues for generations until the offspring consistently have the useful characteristic farmers or scientists are looking for. Cross-breeding is a type of selective breeding except with animals from two organisms from the same species but not the same breed. Selective breeding is one of the most common causes for a wide range of breeds in animals and varieties in plants. this is incorrectIt is the process which humans use animal breeding and plant breeding to selectively develop particular characteristics by choosing which typically animal or plant males and females will sexually reproduce and have offspring together
What is breeding of plants and animals with certain traits to produce offspring with those traits?
artificial selection
How do humans produce animals with certain desirable characteristic?
Humans produce animals with certain desirable characteristics through selective breeding.
