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.

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 important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
Is the population bottleneck an example of natural selection?
No. Population bottleneck refers to a period in which the size of a population becomes much reduced, thereby reducing the number of alleles in the gene pool - and 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.
What is the process that allows for genetic diversity in populations is?
Sex.
When sex cells randomly combine during fertilization to produce offspring there is?
increase genetic diversity
Has genetic diversity helped or hurt the survival of the rat population?
Genetic diversity would increase the survival of the rat population because they would be more capable as a species of surviving in different environments.
Which process performs genetic recombination?
Genetic Recombination is the exchange of genetic information in order to increase the genetic diversity of the population. Probably only with bacteria.
What type of cell reproduction is more likely to increase genetic diversity?
Sexual reproduction is most likely to increase genetic diversity.
Does sexual reproduction increase or decreases genetic diversity?
increase
What effects does union of haploids in fertilization have on genetic diversity?
Fertilization is random and the haploids are male and female gametes, sperm and eggs. So, genetic diversity is enhanced greatly because random fertilization comes after the independent orientation of male and female chromosomes plus crossing over in meiosis. So, statistically speaking, there are myriad variations that can come out of haploid random fertilization and so great genetic diversity is also enhanced here.
Does sexual reproduction increase genetic diversity?
Yes
What is the main purpose of sexual reproduction?
Increase population genetic diversity beyond that possible with asexual reproduction. This makes the population more resistant to disease and parasites.
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection results in less genetic diversity in a population.
What is the variety of genetic material within a species or population is called?
Genetic diversity refers to the variety of genetic material within a species or population. It includes different gene variations and DNA sequences present within individuals of the same species. Genetic diversity is important for a species' ability to adapt to changing environments and for the overall health and resilience of the population.
What is the cellular process that has the goal is to increase genetic diversity?
meiosis
What describes a population at great risk for genetic diversity?
The number one cause of risk to genetic diversity in populations is the size of the population. The smaller the size in an area, the less diverse genetically the population is.
