What is selective breeding cause by?
Selective breeding is caused by humans, we created selective breeding by finding out that if we mate two lions one with white lion gene (and white fur) and one with out the gene (with normal fur )there is a good chance that a white lion may be born but also a good chance a normal lion may be born
What cause variations in a species?
in gene pool, it comes from a random mutation
Does selective cross breeding cause infertility?
No, in most cases it doesn't. Cross-breeding is actually supposed to enhance fertility, especially when crossing on purebreed with another to get an F1 animal.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
Does a sunflower grow in saltwater or freshwater?
Salt water will cause plasmolyzed cells which will kill the plant. Through selective breeding, however you can get a plant that will live in salty soil.
Which crisis can be improved by selective breeding?
Selective breeding has been a way of enhancing preferable genetic qualities in mainly dogs, cats and horses . Often the results can cause mild to severe problems.For example ;breeding for the flat face of the pekingese can cause breathing problems and jaw and teeth deformities. The English Bulldog has been bred to exhibit a certain conformation and in doing so , many of this breed suffer the above conditions as well as reproducing naturally.Artificial inseminations and caesarians are not uncommon. Selective breeding done by qualified professionals can certainly maintain and even improve a breed,as long as the results sought aren't exaggerated.
Does selective breeding benefit farmers?
Selective breeding can provide a preferred quality of food for the farmer. This means that the food produced will be preferred by customers, resulting in a larger sale and profit. Selective breeding can also increase the percentage yield of the food produced.However, selective breeding often means breeding the animals with relatives to achieve the 'ideal' quality. This results in a greater chance of genetic diseases being passed on. It also means that very little new genetic material is introduced into the gene pool, which means that most animals will have similar genes. When this happens, a new strain of disease could easily wipe out the entire farm as there is little variation between species.This also applies to plants.Another Opinion:Actually there's a few holes in the above answer, especially the second paragraph. Selective breeding is not just about line-breeding or inbreeding. Selective breeding is about selecting and breeding those animals that are best suited to meet the standards set by a producer. The animals that are not ideal for the goals and objectives that the producer has in mind, which are called inferior livestock, are simply culled from the herd or flock.Inbreeding or linebreeding is used as a means of selective breeding, but only has a means to purify a particular breed, to allow genetic abnormalities to raise their ugly heads in order to see which animals are carriers of these genetic diseases and whether they should be culled or not. Sure inbreeding could cause animals to have a poorer immune system, but that's only if a producer gets really careless with the inbreeding program and has no herd health or biosecurity program to prevent this from happening.So yes, selective breeding does benefit producers but only if it's used with care and a bit of common sense.
How does variation work to help cause evolution?
You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.
How does selective breeding cause problems?
The fact that it can end up kill of the alleles (other breeds of organism) so you only end up with one breed and all the other can end up being killed of!
What are some reasons for selective mutism?
i have selective mutism myself and there is really no cause for it other then you have it in your genetics
Why is variation important to survival of a species?
Hats off to Sir Charles Darwin for his theory of evolution! Variations are very important to species. Some of the variations are more suitable for the species to survive. You get new species with time by selection of the better ones.
What does spatial isolation cause to lead to speciation?
Normally, a population would split into two species by being physically isolated. However, if two groups of a species develops different breeding behaviors, the populations may continue do differentiate until they can be classed as separate species.
