Allele frequencies in a population tend to remain the same from generation to generation unless acted on by outside influences?
This concept is known as the Hardy-Weinberg equilibrium. It states that, in the absence of evolution forces, allele frequencies will remain constant over generations in a population. It can be used to predict the frequencies of different genotypes in a population if certain conditions are met.
What is the difference between the Bottleneck Effect and the Founder Effect?
The bottleneck effect occurs when a population is drastically reduced in size, leading to a loss of genetic diversity. The founder effect happens when a small group of individuals establishes a new population, carrying only a fraction of the genetic variation present in the original population. Both can result in genetic drift and lead to decreased genetic diversity within a population.
What did Hardy and Weinberg discover about the frequencies of alleles from one generation to the next?
Hardy and Weinberg discovered that under certain conditions, the frequencies of alleles in a population remain constant from one generation to the next. This is known as genetic equilibrium, and it occurs when no evolutionary forces are acting on the population, such as mutation, genetic drift, migration, or natural selection.
What two process can led to inherited variation in population?
Inherited variation in populations can result from two main processes: genetic recombination during sexual reproduction, which shuffles existing genetic information to create new combinations, and mutations, which introduce new genetic changes into the population's gene pool. These processes contribute to the diversity seen within a population and can drive evolution over time.
When allele frequencies are not changing it is called?
BottleneckThat is a condition of the Hardy-Weinberg law and the population is said to be in Hardy-Weinberg equilibrium , but it is an idealization that never happens in nature.
The situation in which allele frequencies of a population remain constant is called?
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.

What role does genetics play in the variation seen in this leafhopper population?
Genetics play a significant role in the variation seen in the leafhopper population as it influences traits such as coloration, size, and behavior. Genetic variation results from differences in the DNA sequences of individuals, leading to phenotypic diversity within the population. Natural selection acts on this genetic diversity, shaping the adaptations that are advantageous for survival and reproduction in the leafhopper population.
What are the steps of meiosis directly responsible for some of the genetic variation seen in a given population?
Independent assortment, crossing over.

How do species get their traits?
Species inherit their traits through a combination of genetic material passed down from their parents and random mutations that occur over time. These traits can be influenced by natural selection, genetic drift, and gene flow, leading to the diversity of traits seen within a species.

How does genetic variation affect the type of traits of adaptations in the individuals of a species?
Variation in and of itself does not affect the traits seen in the overall population. This is because gene frequency and subsequent changes in phenotype generally occur only when the phenotype is "selected" for or against in a population. Granted increased genetic variation is the potential for change, however just as in physics potential has to be acted on for change to occur.The population of a species represents it's entire gene pool. The Hardy-Weinburg Principle states that the frequency of a gene remains the same as long as it is neither selected for or against.Smaller populations can change rapidly due to genetic drift and isolation (which is more of a twist of random probability than selection, like getting heads ten times in a row tossing a penny) selection translates into change in a larger population.
What is Seen Winterthur 's population?
Seen - Winterthur -'s population is 17,119.
What increases genetic varition?
Genetic variation is a direct results of many sources of genetic material and their unconstrained interaction. The larger the population and the fewer restrictions on how they can be integrated the more diverse the genetic variation. This allows for better natural selection and also reduced the ability of disease from affecting the entire population. The founder effect describes genetic variation in communities established by few people. Inbreeding in small closed communities leads to abundances of recessive ailments. This can be seen in hereditary royal families and closed remote communities.
