How can natural selection and isolation and genetic variation result in the development of a new species?
Yes but only closely related species. If you isolated some canaries for years you could come up with a sub species of canary. but no matter how long the animals were isolated they would still be birds. they would not change into a species other than a bird species even if given millions of years.
What else can I help you with?
How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Does natural selection require genetic variation in order to drive the process of evolution?
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
What mechanism is not a mechanism for genetic variation?
Mechanisms such as gene flow, mutation, genetic drift, and natural selection are all considered mechanisms for genetic variation. Non-genetic mechanisms, such as Lamarckian inheritance or acquired characteristics, are not considered valid mechanisms for genetic variation in the traditional sense.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
Do chnages in timing of genetic control during embryonic development contribute to the variation involved in natural selection?
no
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
What do stabilizing selection directional selection have in common?
They both decrease genetic variation .
Which type of selection tends to increase genetic variation?
Natural Selection.
Does natural selection require genetic variation in order to drive the process of evolution?
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
