What else can I help you with?
For a mutation to affect evolution it must occur in?
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.
Under what circumstances would evolution not occur if?
Evolution would not occur if there is no genetic variation within a population, no selection pressure, or if there is no reproduction and passing on of genes to the next generation.
Evolution can occur at different rates however for evolution to occur there must be?
variation in the traits of organisms, heredity (the ability to pass on those traits to offspring), and differential survival and reproduction based on those traits (natural selection). These elements work together to drive the process of evolution over time.
Which of the following is necessary for evolution to occur?
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
What is the model in of evolution in which periods of rapid change occur is called?
Punctuated equilibrium is the model of evolution in which periods of rapid change occur interspersed with long periods of stability. This theory suggests that species evolve quickly in short bursts of rapid change followed by extended periods of little or no change.
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
Did evolution occur in the permian period?
Yes. Evolution ocurred in all geologic periods.
What are some draw backs of selective breeding?
You do not allow evolution to occur, for you are evolution in selective breeding.
How is variation related to evolution?
The more variation there is in a group of specimens, the more evolution can occur between them.
Why did evolution not occur in down syndrome?
Down Syndrome is a the addition of an extra chromosome and not really related to evolution. It is more of a genetic mutation that causes this event to occur.
How do variations occur?
During evolution, chromosomal cariation in structure cannot occur due to
For a mutation to affect evolution it must occur in?
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.
When will convergent evolution occur?
It already has in some instances
What is a mechanism by which evolution can occur?
Selective Breeding of course!
Under what circumstances would evolution not occur if?
Evolution would not occur if there is no genetic variation within a population, no selection pressure, or if there is no reproduction and passing on of genes to the next generation.
Does evolution continue to occur in organisms today?
Absolutely. Evolution isn't an historical process; it is on-going as long as there is life.
What are the divisions of evolution?
Evolution is sometimes described as macro-evolution, which is the long-term evolution of an entire new species, and micro-evolution, which is largely to do with less significant evolutionary changes within a species. Many creationists accept the existence of micro-evolution, but say that macro-evolution does not occur.
