Which statement best describes a population of organisms if cloning is the only method used to reproduce this population?
If cloning is the only method used for reproduction, then all individuals in the population will have identical genetic material. This lack of genetic diversity could potentially make the population more vulnerable to disease or environmental changes. Additionally, evolution through natural selection would be limited as there is no source of genetic variation for traits to be selected upon.
What would decrease genetic variation in a population?
Inbreeding, genetic drift, and natural selection can decrease genetic variation in a population by reducing the number of different alleles present. These processes can lead to a loss of genetic diversity and increase the prevalence of certain genetic traits within the population.
What difference would you see in a population made up of individuals whose chromosomes experience crossing over frequently compared with the population made up of individuals whose chromosomes don't?
A population with frequent crossing over would exhibit more genetic diversity due to the exchange of genetic material between chromosomes. This can lead to increased variability in traits and potentially higher adaptability to changing environments. In contrast, a population with limited crossing over would have less genetic variability and may be more susceptible to genetic disorders or less able to adapt to new conditions.

What would most likely decrease the genetic variation in the human population?
A widespread disaster would reduce the variety within the human genetic pool by eliminating all but certain segments of the population. A global plague could potentially have the greatest effect, as plagues (see: black plague, Spanish influenza) often will often decimate all of a local population save for those with genetic immunity--thus standardizing that mutation in future populations. Global catastrophe could also inhibit travel, and would limit human reproduction to their immediate region, limiting the genetic range of potential offspring.

What would happen if it were advantageous to be heterozygous?
If it were advantageous to be heterozygous, individuals with two different alleles for a particular trait would have a higher fitness compared to individuals with homozygous genotypes. This would lead to increased genetic diversity in the population and potentially faster adaptation to changing environments. Heterozygote advantage is known to help maintain genetic variation within a population over time.
What is a genetic pool?
A gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Thus the actively interbreeding population of a species is a genetic pool comprising the genes for that species. Should something happen that would separate the breeding population into two populations where the populations could not longer mingle to interbreed, there would now be two genetic pools.

Which factor would most likely disrupt genetic equilibrium in a large population?
Genetic Drift
What would occur as a result of changes in the frequency of a gene?
Changes in the frequency of a gene within a population can lead to genetic variation. This can impact the traits expressed in individuals and influence the population's overall genetic diversity. Over time, changes in gene frequency can result in evolution and adaptation within a population.
What ratio of allele combination do you observe?
The allele combinations observed in individuals are determined by the genetic variations they inherit from their parents. The ratio of allele combinations in a population would depend on the frequencies of different alleles present in that population and the patterns of inheritance of those alleles. These ratios can vary depending on the specific genetic traits being studied.
