What are some advantages and disadvantages of selective breeding in animals?
well some times they come out with deformities not bad ones but there are some risks the advantages is that they come out looking better than ever

Mass selection in animal breeding is when certain animals are chosen for certain desirable traits to pass on. Once those animals are obtained, they are bred to control wha…t traits the offspring have and to create varying lines.
Advantages: It only cuts down the valuable trees that are needed meaning it leaves a larger range of biodiversity. Disadvantages: Selective logging can harm the trees surrou…nding the ones being targeted which can be more disastrous than normal logging as it can cause diseases through the trees. On average, for every tree that is cut down for selective logging, 4 more are injured and are left. that is a large waste of wood, meaning they have to cut down more trees to make up for the wasted wood.
Advantages: Easy to implement In-place sort (requires no additional storage space) Disadvantages: Doesn't scale well: O(n2)
Various advantages of selective distribution include reduced costs, increased market coverage, and better control over sales. Disadvantages may include that it does not co…ver the market well enough or that it becomes difficult to match specific retailers and dealers to your needs.
disadvantage: selective breeding gets rid of variety advantage: selective breeding rules out weakness and disability disadvantage: isn't that what Hitler tried to do with …humans in WWII? do we really want to be like him? Selective breeding(or artificial selection) produces traits which may be advantagious to us, but be a disadvantage to the animal.Here are some examples-The lapps of northern Europe herd and breed the wild deer, selecting docile animals. The resulting herds could not survive in the wild.Cows with big udders are good for us , but are probably painful for the cow. English bulldogs mght be considered a cool looking dog, but have breathing difficulties and such small pelvises that they often have to give birth by causation. Advantages: Can produce fitter, stronger animals or animals of a higher yield of milk, meat or eggs for example. Can produce animals better suited to survive in poor climates or marginal conditions, thus preserving human food supplies and saving life. Can ensure the eradication of hereditary sickness in some blood lines. Disadvantages: For show animals such wild kitten eatingas some dogs, it is practised quite strictly by breeders aiming at a certain look which is set down as the breed "standard"- many Dalmation puppies are euthanased because they do not exhibit the breed standards for example, so there are serious moral questions to it too.Too much close interbreeding to obtain certain cosmetic traits can also result in the amplifying of inherent illnesses - like the bulldogs mentioned above, or German shephered dogs with hip problems and so on - in fact, these issues are rapidly worsening in recent years with dogs in particular. keep in mind it will eat your babies if you anger them.
1 answer is the animals that are in captive breeding cannot be harmed by forest fires, flooding or other species of animals Answer 2: animals are protected in an in - built… habitat and are protected from hunting and poaching so is their habitat. the disadvantage is that sometimes people don't take god care of the animals. so it does more harm than good. another disadvantage is that there is no control over the long term issues i hope this helps
An advantage of selective breeding is that producers can produce cows or bulls with characteristics that improve the breed or the herd itself, or produce more income for the p…roducer when calves are sold. Selective breeding means herd improvement, on things such as milking ability, mothering ability, carcass quality, forage utilization efficiency, calving ease, stayability, birth weights, weaning weights, etc.
Selective tendering has a low cost for production of tender documents since there is a small list of selected firms to tender. Price will be the main determinant for selection…, since all other considerations would have been done already making the analysis process simple and faster.
farmers selectivly breed cattle to get the characteristics they desire for the job they are going to put the offspring to do
advantages: we get more breeds and more animals/plants easier people can make more more Disadvantages the animals/plants can have genetic diseases It is har…d to get rid of the genetic diseases because you have to breed them out
The selection index is where you have to score your selected animal you are going to breed. You first choose 5 or 6 criteria which is important to you such as good temperament…, long legs etc. You then merit score how good your animals are between 1 and 10. Then you weighting which is giving your criteria a score between 1 and 4, you score this on how important each criteria is to you if you want in the young offspring. You then times the merit score by the weighting score for each criteria and then add them all up and put the score over 150 which is the maximum score than can be giving. You then find the percentage of that.
If it is an animal, it would be unfair to the animal, it could cause genetic problems and the animal could get sick easier. If it's a plant, it could cause environmental probl…ems if it uses more water than other plants around it, causing the plants around it to dry out and birds to lose homes and insects to lose food. It all depends on what it is.
There are many advantages but I will keep this short 1. For quantaty: to breed animals for foods in large amounts 2. For selective breeding: to improve certain qualities in br…eeds of animails by breeding the male with the best qualities with the female with the best qualities. This happens in nature with the Alpha male and Alpha female breeding (natural selection), but people for centuries have been breeding certain animals with the right qualities to improve them for our own purposes - ie this is where we get certain dog breeds from (all domesticated dogs come from wild dogs such as wolves, but the 'wolf' DNA is nearly completely bred out of them nowadays). Other examples - horses (for racing, pulling carts, hunting, etc), cows (for best milk, meat, showing), etc, etc....
Selective breeding helps to rule out weakness and disability in animals and helps make farming more lucrative for farmers by providing more robust animals for sale. Corn woul…d only have ten kernels or less per ear withour selective breeding!
Advantages: * determines the fitness of an organism by direct application. * employs a wide range of criteria * provides for opportunism Disadvantages: … * involves a lot of chance. * some organisms escape the full range of possible criteria * is under employed in boom times, over-employed in lean times. * recessive traits 'hide' from the process. *
cross-breeding it may result in getting more and giving the combination of different breeds.
depending the trait you find most desirable on the animal. like if i want the charcoal color of a Siamese cat's ears, then i would breed the cat, and whatever kitten has that …trait, get the kitten, then breed it again
