What are the stages for selective breeding?

Answer 1

Overproduction :organisms produce more offspring than the environment can support. I herited Variation :organisms are very different have variation in there genes that causes them to have different them to have different traits that are passed don to their offsprings.Adaptation Different traits can offer advantage in different environments. Natural Selection :over time the useful trait will become more common in the population always remember VANS

Answer 2

Selective breeding is when you mate specific plants or animals to pass on a certain genetic trait they may have. For example, if you have two horses with very strong hearts then you may want to breed them so that their offspring may also have a strong heart. Farmers use selective breeding to breed the best plants and animals for feeding, selling or breeding.

Answer 3

1overproduction variations competition selection survival
21. environmental pressure 2. competition for resources 3. selection for fittest phenotype 4. greater reproductive success 5. frequency of genotype increases
31. variation 2. struggle for existence 3. survival of the fittest 4. genetic change 5. adapt to environment
4overpopulation variation competition survival of the fittest reproduction of survivors
5overproduction variation competition selection survival & reproduction
61. individuals within a species show genetically determined variation. 2. organisms within a species typically produce more offspring than are needed to replace the parents when they die. most of the offspring die. 3. the excess number of indivuals results in a shortage of specific resources. 4. due to individual variation, some individuals have a greater chance of obtaining needed resources and therefore have a greater likelihood of surviving and reproducing than others. 5. as time passes, the percentage of individuals showing favorable variations will increase with the percentage showing unfavorable variations will decrease.
71. overproduction. 2. genetic variation. 3. environment changes 4. best adapted

survive

+ reproduce 5. over time, population will change due to the changes.

81. overproduction 2. genetic variation 3. change in environment 4. survival + reproduction 5. change in species
91) gene based variation 2) challenges to reproduce 3)organisms reproduce more offspring than environment can hold so they have to compete 4)organisms that are better coped are more likely to stay alive 5)traits best suited to the environment will increase in population and lead to change in the species over time
101. produce offspring that survives 2. environment is hostile and contains limited resources 3. organisms differ in the traits they have 4. some inherited traits provide organisms with an advantage 5. each generation contains proportionately more organisms with advantageous traits.
111. organisms produce more offspring than can survive. 2. differences, or variations, occur among individuals of a species. 3. some variations are passed to offspring. 4. some variations are helpful. individuals with helpful variations survive and reproduce better than those without these variations. 5. over time, the offspring of individuals with helpful variations make up more of a population and eventually may become a separate species.

Answer 4

Artificial selection is the process of breeding plants and animals with specific traits only. Generally, the breeding is done in a controlled environment to ensure the outcome the breeder desires.

Answer 5

First, you get two dogs; hypothetically strong dogs, this will be to pass on the trait of their strength to their offspring. Then make them shag to make their offspring a strong dog. Then you take the nucleus of the mother dog and implant it into the offspring dog.

P.S: When they are breeding they must do it doggie style.

thair must be a tree near by and a rainbow!!!

it has been proven!!!!!!!!!

Answer 6

1. over production 2. genetic variation 3. struggle to survive 4. successful reproduction
