Populations with high levels of genetic diversity are likely to adapt to changes in the environment?
True, as is the opposite
What characteristic do a bottleneck and a founder effect have in common?
The founder effect a genetic bottleneck are similar in their effect on the genetic diversity of a local population in both situations. They result in the development of a population from a small number individuals and is likely to have reduced genetic diversity.
How does an organism benefit by being able to reproduce both sexually and asexually?
During good conditions, organisms can reproduce sexually and benefit from the genetic diversity that this creates. During harsh conditions, asexual reproduction can take place without having a partner and results in offspring that are identical to the parent. This means that if the parent can survive the harsh conditions, then the offspring are more likely to as well.
What would most likely decrease the genetic variation in the human population?
A widespread disaster would reduce the variety within the human genetic pool by eliminating all but certain segments of the population. A global plague could potentially have the greatest effect, as plagues (see: black plague, Spanish influenza) often will often decimate all of a local population save for those with genetic immunity--thus standardizing that mutation in future populations. Global catastrophe could also inhibit travel, and would limit human reproduction to their immediate region, limiting the genetic range of potential offspring.
Why is sexual reproduction important in terms of evolution?
sexual reproduction involves 1) mixing of 2 genomes 2) recombination of homologous chromosomes. Both lead to genetic variation (polymorphism) and polymorphism means that if environmental conditions change, the organism has a higher chance that it possess genes which will let it survive.

How could cloning help save endangered animals?
Cloning may be a quick fix to increase the number of individuals. However, numbers are not everything. What is more important to small population sizes is genetic diversity, in other words the amount of genetic variation that exists within a population. Populations with significant reduction in genetic diversity will have a drastically increased likelihood of producing offspring with a recessive genetic disorder (the same reason why inbreeding in humans will likely result in some problem with the child). Besides this, genetic diversity allows populations to adapt in the event of a strong environmental change (e.g. climate change). In other words, if the environment changes, diversity makes it likely at least some of the individuals are adapted to survive.
How could greater genetic diversity have lessened the devastation of the potato blight?
Some potatoes would be more likely to have a genetic resistance to the disease and survive. (Study Island)
What is generated by asexual reproduction?
Always during asexual reproduction, the offspring will be genetically identical to the parent. In plants, there are different types of asexual reproduction;budding, vegetative propogation, fragmentation, binary fission, and spores. Just say is a disease or an environmental change came into a field with plants that were identical, the genetically identical plants would mostly likely not survive due to no genetic diversity. Asexual reproduction can happen during mitosis, not meiosis.
What characteristic do a bottleneck and a founder effect have in common?
The founder effect a genetic bottleneck are similar in their effect on the genetic diversity of a local population in both situations. They result in the development of a population from a small number individuals and is likely to have reduced genetic diversity.
What types of population does genetic drift affect?
Isolated populations can lose genetic diversity through genetic drift. This is because some alleles can be lost by chance. Many more homozygous individuals are likely.
Which sequence if natural events is likely to lead to ecosystem stability?
1) Sexual Reproduction - Genetic variation - Biodiversity - Ecosystem Stability
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
How might the lack of genetic diversity found in populations of endangered species might hinder their recovery?
Lack of genetic diversity can becomes a problem when a species is hit with infectious diseases. If all the organisms are very similar, then it is very likely that they will all be affected by the same disease, thus destroying the species as a whole. In species with high amounts of genetic diversity, a disease may destroy a section of the population, but many individuals will be resistant to the disease.

Which of the following is least likely to be a source of genetic variation among living organisms?
Things that kill the organism, such as, immature lungs at birth.
