What else can I help you with?
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Genetic drift can best be described as?
D) the change in frequencies of alleles due to random events
Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.
What small genetic change such as a single mutation may result in?
genetic drift....
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.
How can a genetic drift be explained in biology?
A genetic drift is explained in biology as a gene variant changing frequency. Genetic drift can cause genes to disappear and not be passed onto the next generation.
Name the vocabulary term that describes the alteration of allelic frequencies by chance events alone?
Genetic drift.
Is genetic drift of product of genetic change?
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.
Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Genetic drift. It refers to the random fluctuation of gene frequencies in a population due to chance events, particularly in small populations. It can lead to the loss of genetic diversity and the fixation of certain alleles over time.
Is genetic drift an adaptive change?
Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.
What are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
