What question did hardy and Weinberg want an answer?
Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
How does variation within a clade affect clade's chance of surviving environmental change?
Variation within a clade increases the likelihood that at least some individuals will have traits that are advantageous in the face of environmental change. This genetic diversity allows for some members of the clade to survive and reproduce, passing on their beneficial traits. As a result, clades with greater variation are more likely to adapt and survive in changing environments.
How is change by natural selection different from change due to a mutation?
Change by natural selection occurs when certain traits provide a survival or reproductive advantage in a given environment, leading to those traits becoming more common in a population over generations. In contrast, a mutation is a random change in an organism's DNA that can introduce new traits. While mutations are the source of genetic variation, natural selection acts on that variation, favoring beneficial mutations and weeding out harmful ones. Thus, mutations are the raw material for evolution, while natural selection is the mechanism that drives adaptive change.

How can mutation lead to evolution in a population?
Mutation introduces variation in the genetic material of individuals within a population. This variation can result in different traits that may provide a survival advantage in a particular environment. Over time, individuals with beneficial mutations are more likely to survive and reproduce, passing on these advantageous traits to their offspring, ultimately leading to evolutionary change in the population.

What do changes in the DNA sequence or mutations help drive?
Changes in the DNA sequence or mutations can drive evolution by introducing variation within a population. This variation can provide individuals with different traits that may be beneficial for survival and reproduction in a changing environment. Over time, natural selection acts on this variation, leading to the gradual accumulation of advantageous traits in a population.
What are 3 basic components to today's theory of evolution?
Three basic components of today's theory of evolution are genetic variation within a population, natural selection acting on this variation, and the inheritance of traits that confer a survival or reproductive advantage.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution.

How is genetic variation related to species chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
How is genetic variation related to a species's chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
Why are mutations importasnt to the modern theory of evolution?
Without beneficial mutations leading to beneficial variation there would be no natural selection on the individual organism, outside of sexual recombination, which would mean no change in allele frequency over time leading to no evolution. Fortunately, that is never the case in nature and mutations lead to variation and adaptive change in the organisms under selection pressure.
What is a mutation and how does it relate to evolution?
A mutation is a change in the DNA sequence of an organism. Mutations are sources of genetic variation, and they can drive evolution by introducing new traits that may be advantageous, neutral, or harmful in different environments. Over time, beneficial mutations can be selected for, leading to changes in the population and contributing to the process of evolution.
What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
How does variation work to help cause evolution?
You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.
How is genetic variation related to a species chance of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
