Interbreeding among members of a population results in?
no changes in the relative frequencies of alleles in the gene pool i think...
What does the Hardy Weinberg principle predict?
Genotype frequencies in a population.
What are more than two alleles that exist in a population for a particular trait?
Multiple alleles
What is evolution in genetic terms?
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
How do alleles influence natural selection?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
In what kinds of situations is genetic drift likely to occur?
Genetic drift may occur when a small group of individuals colonizes a new habitat. These individuals may carry alleles in different relative frequencies than did the larger population from which they came.
What is evolution genetic terms?
Any change over time in the relative frequency of alleles in a population.
What indicates that evolution is occurring in a population in genetic terms?
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
Are new alleles made by natural selection?
No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
How do mutations relate to variations within a population?
Essentially, they are what directly causes evolution. Evolution is the shifting of allele frequencies in a population. Variant alleles come into existence through reproductive shuffling, mutation. Natural selection is what then determines in what 'direction' the allele frequencies in the population gene pool shift, whether some variant allele spreads throughout the population, or fades from it.
What is meant by the allele frequency?
An allele frequency measures how common certain alleles are in the population. "The distribution of alleles in a population" -Apex
