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.

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 to 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 a 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?
Generally, yes. To have a wide variation in a population of organisms means that your population is better able to meat environmental challenges and survive through an onslaught of parasites, such as bacteria and viruses.
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.
What is the advantage of sexual reproduction in terms of genetic diversity and adaptation?
Sexual reproduction allows for genetic diversity through the mixing of genetic material from two parents, increasing the chances of beneficial traits being passed on to offspring. This diversity enhances the ability of a population to adapt to changing environments and challenges, ultimately increasing its chances of survival and evolution.
How is genetic diversity beneficial to a species and its survival?
Genetic diversity is beneficial to a species because it increases the chances of survival in changing environments. It allows for adaptation to new conditions, resistance to diseases, and overall resilience. A diverse gene pool provides more options for natural selection to work with, ensuring the species can evolve and thrive over time.
How do DNA mutations impact genetic diversity and evolution?
DNA mutations impact genetic diversity and evolution by introducing new genetic variations into a population. These mutations can lead to changes in traits and characteristics, which can be beneficial, harmful, or neutral. Over time, these variations can be selected for or against through natural selection, influencing the overall genetic makeup of a population and driving evolution.
Which race has the least genetic diversity?
The race with the least genetic diversity is the indigenous peoples of the Americas.
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.
