It allows for variation within a species leading to a larger gene pool.
It is an advantage because variation within the DNA of a species prevents a disease being able to harm or kill the entire species. Some of the species will be immune to the pathogen.
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
The differing traits provided by variation mean that at least some groups of the species may be better prepared to survive.
Some genetic variation exists in members of the same species because of variation among individuals due to environmental factors.
Sometimes positive variation can improve some ability of the species adapted to the environment. For example, a kind of virus can be killed by medicine A. A small part of the virus has some variation that make it can be alive with medicine A. The species of the virus can exist in future, or it will disappear in the future in the environment full of medicine A. Besides, positive variation can provide some capacity for the species to get more resource in the competition. Of course, there is negative variation that might contribute to the disappearance for the species. That is just another side of variation.
Some examples include Staphylococcus species, Streptcoccus species, and Enterobacteriacae species.
There is some variation based on species of mouse. Laboratory mouse has 40 while a deer mouse has 48 as examples.
This is impossible to answer as there is every variation imaginable, and none, within bird species as a whole. The only catch-all answer is DNA or surgical sexing. With some species, the male will be more colourful than the female. However, with many species, there is no difference in colour. Within some bird species, the female may be smaller than the male. This, too, will vary in other species. Some species may be best told apart by the sound they produce and how they communicate.
a different form of an animal; adaption
There are many many species of mussels but their anatomy is pretty much the same with some variation that distinguishes them as species.
A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
There are several causes for variation that occur within a population. Some of these causes include neutral mutations, sexual reproduction, and diploidy.
Some variation in a species may be a life line for that species if something like a pathogen would attack it and those that are slightly different would have a good change of living while others might not. This is really what evolution is all about.
group of species
Sexual reproduction means there is much greater scope for genetic variation of offspring. Variation is good for any species as it is this variation that allows for adaption e.g. the variation might provide some individuals with resistance to a new disease that affects the species, hence those individuals survive and thrive.
Variations within species are triggered by their needs in order to take better advantage of their environment, to attempt to overcome certain obstacles to survival, predators, etc. Perhaps some good examples (an expert would give better ones, I suppose) would be the hedgehog, that developed spikes to protect itself from predators, or cheetahs that developed good muscles in their legs to run faster than their prey.
some advantages in sexual reproduction are *genetic variation *to have different abilites which species can survive
Some Eucalyptus species...
No. Without some differences there woul be nothing to select.
there is variation among the members.
Beluga wales, bats, dolphins, and some species of birds.
