Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

/hich of the following is an example of disruptive selection? O Short weeds that grow close to the height O Dark-colored moths that hl survive to reprod
In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.
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.

Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
If both the forces of mutation and natural selection are acting on this population from generation to generation (and have been acting on this population for many many generations), what do you predict will happen to allele frequencies over successive generations? Allele frequencies will remain constant The frequency of the D allele will increase The frequency of the d allele will increase
The graph below shows the change in a lizard population over time. Changes in Allele Frequency Over Time DC Year 1 Year 50 Key = proportion of population with two copies of allele Z Which process most likely led to the change in the lizard population? Natural selection acting on a harmful trait. O Natural selection acting on a beneficial trait. O Natural selection acting on a recessive trait. Natural selection acting on a sex-linked trait.
Gene flow often increases genetic diversity of populations that come together. Which of these is an example of when gene flow could reduce genetic diversity if two populations (Population A and Population B) come together? O The offspring with parents from population A and B have low survival because they are not adapted to the environment. O Individuals from population A have an allele that is not found in population B. O Individuals from population B have an allele that is not found in population B O Population A only has homozygous recessive alleles and population B only has homozygous dominant alleles.
Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of references

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.
When individuals enter or leave a population, the gene frequencies change. Migration interferes with nonrandom mating. Deer mice are usually found in the woods and are dark brown in color. The deer mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. How does this information illustrate nd 2 natural selection? * chool Speciation occurs when groups are geographically isolated. The population evolved when the gene frequency remained the same. Individuals, not populations, evolve. A variation helped individuals to survive in their environment and to pass on their genes to the next generation.
If natural selection is the only force acting on this population from generation to generation, what do you predict will happen to allele frequencies over successive generations? The frequency of the d allele will increase Allele frequencies will remain constant The frequency of the D allele will increase
