Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
Could you define Minor and major allele frequency?
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
What is the distribution of a particular allele within a population called?
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
What happens when a population is in weinberg equilibrium?
Allele frequency is stable
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
How is variation beneficial to a population of organisms?
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
Describe what is occurring when a population is said to evolve?
The allele frequency of the populations gene pool is changing.
What Is the percentage of a particular allele in a population?
Allele frequency.
What effect does a bottleneck have on the allele frequency of a population?
It greatly reduces the total population, which increases the effects of genetic drift on allele frequency.
What is allele fixation?
An allele present in all members of a population
What is meant allele frequency?
How often a certain allele (or trait) occurs in a certain population.
Could you define Minor and major allele frequency?
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
What is the distribution of a particular allele within a population called?
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
