in crossing over the gens present on chromosomes forms linkage so the character are exchange & thus it lead to recombination of genes that affect genetic diversity

How do captive breeding programs affect genetic diversity?
Captive breeding programs can affect genetic diversity in one of two ways. Within the program itself, genetic diversity is reduced, because captive breeding programs only have a limited number of animals to work with. On the other hand, animals from a captive breeding program that are re-introduced to the wild can increase genetic diversity, because they are bringing genes that may have been gone for a long time back into the gene pool.
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.

How does genetic variation affect the type of traits of adaptations in the individuals of a species?
Variation in and of itself does not affect the traits seen in the overall population. This is because gene frequency and subsequent changes in phenotype generally occur only when the phenotype is "selected" for or against in a population. Granted increased genetic variation is the potential for change, however just as in physics potential has to be acted on for change to occur.The population of a species represents it's entire gene pool. The Hardy-Weinburg Principle states that the frequency of a gene remains the same as long as it is neither selected for or against.Smaller populations can change rapidly due to genetic drift and isolation (which is more of a twist of random probability than selection, like getting heads ten times in a row tossing a penny) selection translates into change in a larger population.
What factors affect biodiversity?
Ecosystem, genetic and cultural diversity, and the connections between these and all species.

Give three types of biodiversity essential in preserving ecological systems and functions?
Three types of biodiversity that are essential in preserving ecological systems and functions are genetic diversity, species diversity, and ecological diversity. Genetic diversity is a measure of the variety of versions of the same genes within individual species. Species diversity describes the number of different kinds of organisms within a community or ecosystem. Ecological diversity means the richness of complexity of a biological community.
What are the Technologies that affect biological diversity?
Technologies that affect biological diversity include genetic modification. This will cause a loss in biodiversity.
How do captive breeding programs affect genetic diversity?
Captive breeding programs can affect genetic diversity in one of two ways. Within the program itself, genetic diversity is reduced, because captive breeding programs only have a limited number of animals to work with. On the other hand, animals from a captive breeding program that are re-introduced to the wild can increase genetic diversity, because they are bringing genes that may have been gone for a long time back into the gene pool.
How does adaptations affect the diversity of a species?
Adaptations make the species different from other species, and if they are passed down, they will make more species with these differences.
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.
How does land that gets broken up contribute to loss of species diversity?
When land gets broken up, such as through continental drift, animals are separated. Each section of land initially contains a smaller population of animals. There are fewer mating choices, which decreases species diversity.
What does the word biological diversity mean?
Diversity among and within plant and animal species in an environment. It means that each plant and each animal in an ecosystem is not exactly the same. If something like an infection or disease would affect a species, some would not be affected while the others would not.
The factors that affect the species diversity?
-Invasive species- When a new species that is not native moves into an area, it often won't have natural predators and can thus survive better than natives. They take over, and lower diversity levels by killing off other species -Keystone species- a keystone species is a species which many others in the food chain rely on, if the keystone species has a problem or decrease in population the diverersity of the population will also decrease. - Availability of resources- For instance food, shelter, nutrients, notice that rain forests which are abundant in rain forests show much diversity, while a tundra shows very little diversity. - Stability of the community- for instane, tempreture shifts will cause a decrease in diversity because certain species have a small range of tempreture that they can live in. This is why coral reefs are decreasing in diveristy, they are very limited in teh tempreture they can live in. I wouldn't agree that natural selection affects diversity levels as it is present at all times, in every ecosystem and does not fluctuate.
How does racism affect diversity?

Differentiate between a highly modified and least modified ecosystem in terms of natural resources?
In natural ecosystems there tend to be more niches and a higher diversity of species compared to most managed agroecosystems that are simpler, have fewer predatory and parasitic species, and less genetic diversity within a species.
