What is the difference between anatomical anomaly and biological variation?
Biological variation is much wider term. It takes place at the level of species while anatomical anomaly means a anatomicaly different individual within species.
How can genes be altered and combined to create genetic variation within a species?
Through different types of mutations.ChromosomalinsertiondeletiontranslocationinversionGenesubstitutioninsertiondeletion
What are the function and benefits of biodiversity?
Biodiversity describes the different life forms found within an ecosystem. It is a measure of the health of an ecosystem and greater biodiversity implies greater health. See the related links for more information.
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
What are specific examples of variation within a species?
Human species, as in the variation in height.
What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Which process produces the most variation within a species?
Variations occurs in species due to the process of "Crossing over"
What term describes changes that within species?
variation
What causes variation within a species?
It has adaptations
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
How do the Grants data show that genetic variation is important in the survival of a species?
The Grants' work shows that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
Is adaptations a genetic basis for variation within a species?
No, adaptations usually do not result in any genotypical change in a species.
How does variation within a species increases its chance to survive when the environment changes?
The differing traits provided by variation mean that at least some groups of the species may be better prepared to survive.
