Which process produces the most variation within a species?
Variations occurs in species due to the process of "Crossing over"
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 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.
Discuss how 1 variation within a species 2 geographically isolated populations and 3 fossil organisms make it difficult to clearly define a species?
what is this, your homework? yes and its hard.
What characteristic witin populations causes natural selection to occur?
The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.
What causes variation within species?
Variation within species can be caused by genetic mutations, environmental factors, and interactions between genes and the environment. Genetic mutations are changes in the DNA sequence that can create new traits. Environmental factors, such as diet and climate, can also influence variation by selecting for certain traits over others.
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
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.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
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 characteristic within populations causes natural to occur?
genetic variation
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.
