Best Answer

Yes. The basic definition of evolution depends on changes in the frequency of alleles in a population.

Does convergent evolution result in speciation?

All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.


What are some examples of divergent evolution?

All reproductively isolated populations diverge genetically. Even in cases where convergent evolution occurs, this is only at the behavioural and morphological level. At the molecular and the genetic level, even these instances still diverge at the genetic level.


What genetic change is always a result of evolution?

Evolution is not a cause of genetic change: it is the effect of genetic change.


If genetic mutation almost always leads to sterilization and death then how can evolution be true?

Genetic mutation does not always lead to sterilization as you point out. This however is not the way evolution happens. Evolution occurs mainly through small adaptive changes over a long period of time that are not mutations. Evolution does not happen suddenly.


What is evolution and why does it happen?

Evolution is when a species develops and diversifies at the genetic level to better fit it's environment . Evolution is natural , and occurs so species can survive . Scientifically speaking , when the earth was created , there were only single-cell bacteria around . If they hadn't evolved , they probably wouldn't have survived the ice age , etc .


A random change in a population's allele frequency?

Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.


Are adaptation genetic?

Yes, physical adaptions are genetic, it's called evolution.


Does polyploidy provide genetic basis in evolution?

no


Changes in the genetic makeup?

Organic evolution.


What is genetic evolution?

Genetic evolution refers to the variations in inherited traits of biological populations over successive generations. It is also referred to as the selfish gene theory.


What is a part of macro-evolution?

Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.


What is the genetic definition of evolution?

Evolution is the change in allele frequency over time in a population of organisms.
