What would be the result if crossing over didnt happen during meiosisin humans?
There would be less genetic variation in humans
How does having a diverse gene pool help a species survive?
It creates genetic variation within the species allowing them to adapt to changes in their environment through the process of natural selection. Species without genetic diversity are at a greater risk for unhealthy reproduction because they will have a greater tendency to produce offspring with recessive genetic diseases.
If bacteria in a colony are unable to perform conjugation how would this hurt the colony's chance for survival?
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
What happens to a population when genetic variation decreases?
Less sex mutation and changes in DNA, I think?
How does variation work to help cause evolution?
You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.

What would happen if crossing over didn't happen during meiosis in humans?
There would be less genetic variation in humans
Which would most likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.

What are populations with low genetic variation less likely to do?
I don't f*****g know
Does genetic drift increase or decrease genetic variation in populations and why?
It is important to understand that each individual has different genes. Genes can be lost if an individual dies without reproducing. To answer your question: There are two type of effects caused by Genetic Drift. The founder effect happens when a few species inhabit a new territory. If only those species reproduce then there are less genes in the gene pool and that leads to less variation. This can happen if storms sweep birds to a previously uninhabited island. The other effect is the bottleneck effect. This happens if a disease or poaching drastically reduces the number of individuals in a population. Since there are less individuals who can reproduce there are not as many genes that can be passed down.
What factors increase a species chance to become extinct?
Less space for habitat, few populations, small population size, lil generic variation, being hunted by by humans
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
How is natural selection done?
Genetic mutation and variation are the main drivers of phenotype characteristic differences among species. The organisms in a population that are better suited to survive and reproduce, survive and reproduce (propagate) more than the organisms that are less suited. Add to that sexual selection and you get a wide variety of species that seem to have been designed but were sculpted by blind processes. The process of genetic mutation and variation is not a hypothesis but a scientific theory that is based on observable facts and evidence.
Why genetic engineering is superior to selective breeding?
Genetic engineering: -more specific changes -changes are more controlled -takes less time to enact -lack of variation
Dinobryon is a species of protozoa that reproduces asexual. How can this asexual reproduction be harmful to the species?
They have less genetic diversity in their population.
Dinobryon is a species of protozoa that reproduces asexually . How can this asexual reproduction be harmful to the species?
They have less genetic diversity in their population.
