Mutations are the raw material for evolutionary change, without mutations there could be no new variations among members of a population. Group of answer choices True or false

Suppose there is a type of deleterious mutation in a particular human gene that causes death very late in life. Such mutations happen in about one in every million births, and can be passed on to descendants. Which statement about this allele is false? At equilibrium, the frequency of this allele will be zero. Selection against this mutation is weak compared to an allele that causes death at an earlier age. Medical advances that extend human lifespan will increase selection against this allele. Selection against this allele depends on the rate of extrinsic mortality.

The raw material for evolution is random mutation. Discuss whether or not you view evolution as a random process.

Which is NOT a component of evolution by natural selection? Group of answer choices Organisms compete for resources. Organisms adapt due to environmental changes. Species are fixed. Individuals have different reproductive success.

Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies

This mechanism of evolution occurs when populations migrate. extinction gene flow genetic drift natural selection? Give typing answer with explanation and conclusion

In the modern reckoning of evolution by natural selection, what is the most important feature that allows an allele to be more represented over time in a population? The allele makes the organisim stronger. The allele allows the organisim to produce more breeding offspring. The allele allows the organisim to eat more readily. The allele allows the organsims to escape predators readily.

Genetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection. Explain or give an example.

If vestigial traits are no longer useful to an organism, why don't they evolve out of the population? * Individuals with the trait have developed new ways to use them. Individuals that have the trait continue to survive and reproduce, and they pass on th genes for that trait to the next generation. Individuals that have the trait must have some sort of evolutionary advantage. The individuals that have the trait become less common over time.
