What else can I help you with?
If you know the phenotypes of all organisms in a population you can calculate the allelic frequency of the population?
Yes, use the Hardy-Weinburg equilibrium equation.
The theory of modern synthesis states that evolution involves changes in a population's?
population
Which event describes a change where evolution has happened?
An allele frequency changes in a population.
Does natural selection cause a change in the gene frequencies of the population over time?
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
Does evolution occur at the level of the organisms?
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
In A small founding population few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly (six fingers). Many generations that followed had cases of?
The Founder Effect The founder effect is when a few individuals of a species form a new population. The gene pool composition, therefore, is not reflective of the gene pool of the original population. Think of this as a small number of people starting their own colony. This is an example of the Founder effect because Polydactyly is a dominant trait. And in a large population, it will be rare finding a person with a 6th digit. In a smaller population, however, polydactyly has a higher frequency of this allele, because the smaller the population, the higher the sensitivity for inbreeding and lower genetic variation. So, polydactyly (dominant allele) + Increase inbreeding= Higher polydactyly allele frequency.
A small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly . What is an example of?
Genetic Drift

What is the ter of a change in the relative frequency of alleles in population over several generations?
The term for a change in the relative frequency of alleles in a population over several generations is "evolution." This process occurs through mechanisms such as natural selection, genetic drift, mutation, and gene flow, leading to adaptations and variations within the species. Over time, these changes can significantly affect the genetic makeup and traits of the population.
What happens when a population is in hardy wienberg equilibrium?
Allele frequency is stable The phenotype frequency does not change.
A small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyl What is this an example of?
Founder Effect
The graph above shows the frequency distribution of a population of fish before and after scientists engaged in a breeding program over many generations. explanations best describes the program?
The graph likely shows a shift towards larger fish sizes after generations of selective breeding. Scientists likely selectively bred larger fish to produce offspring with desired traits, leading to an increase in the frequency of larger fish in the population over time.
What is the relationship between allele frequency and genotype frequency in a population?
The allele frequency in a population determines the genotype frequency. Allele frequency refers to how often a particular version of a gene appears in a population, while genotype frequency is the proportion of individuals with a specific genetic makeup. Changes in allele frequency can lead to changes in genotype frequency within a population over time.
