When all the organisms are exact genetic copies, you don't have diversity. Additionally they would all appear as identical twins. If you are talking about a food crop if a bacterial, fungal disease strikes, they may all succumb. We would be left without that food. When there is diversity, some of the organisms are resistant. The resistant organisms survive and pass the resistance on to future generations. The resistant organisms also serve as a buffer. The resistant organism doesn't come down with and, therefore, spread the condition.

∙ 13y agoyes! for us we need to reproduce with humans who are less like us (not relatives) because otherwise the offspring will be worse off, and could have serious birth defects or genetic disease. For nature as a whole, it is almost a failsafe. what would we do if we only had 3 crops? there were only a few animals a disease could wipe them all out. Living things rely on each other, wiping out one is very negative for the whole ecosystem it is in (excluding humans, that would improve the environment).

How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
What is the process that allows for genetic diversity in populations is?
Sex.
How does the process of fertilization act to increase genetic diversity within a population?
Random fertilization. All the eggs and sperm produced are variations due to crossing over alone, not even considering other processes. The meet and fertilization occurs randomly insuring a good mix of genetic variation. Thus, genetic diversity.
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.
Why does evolution require diversity within a species?
If everything is exactly the same, there is a lower chance of evolution occurring; diversity is not necessary, but it works quicker. This is because where random mutation is the only thing to introduce wider genetic diversity, it will take a longer time than simply mixing the gene pool up.
How is genetic diversity beneficial a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity to beneficial to a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity beneficial to species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
What is three reasons why a sexual reproduction is beneficial?
genetic diversity more efficient natural selection
How might genetic drift alter the diversity of a population?
Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
Is increasing the genetic diversity beneficial?
Yes, increasing genetic diversity can be beneficial as it can help populations adapt to changing environments, resist diseases, and prevent inbreeding depression. High genetic diversity also promotes ecosystem stability and resilience.
Populations with high levels of genetic diversity are likely to adapt to changes in the environment?
Yes, populations with high genetic diversity have a larger pool of genetic variations to draw from, increasing the chances of beneficial traits emerging in response to environmental challenges. This flexibility allows the population to adapt more effectively to changing conditions compared to populations with low genetic diversity.
How does genetic combination help a species to survive?
Genetic combination increases genetic diversity within a species, providing a wider range of traits and characteristics. This diversity can enhance a species' ability to adapt to changing environments and challenges, increasing its chances of survival and evolution. Moreover, genetic combination can help dilute harmful mutations and increase the chances of beneficial ones being passed on to future generations.
What can mutations do and do not do?
Mutations can introduce genetic variation within a population, which can lead to diversity, adaptation, and evolution. However, mutations do not always result in beneficial changes and can also lead to genetic disorders or diseases.
What is the role of recombinations in evolution?
Recombinations play a key role in evolution by shuffling genetic material from two parents to create genetic diversity in offspring. This genetic diversity allows populations to adapt to changing environments and increases the chances of beneficial traits being passed on to future generations. Recombination helps drive natural selection by providing a wider pool of genetic variation for organisms to evolve and survive.
What 3 examples of biodiversity?
genetic diversity species diversity ecosystem diversity
What is true about the gene pool and genetic diversity?
A diverse community is a community populated by people from many different backgrounds; differences in background such as social, economic, religious, ethnic, or country of origin.
