Population Genetics flashcards #3
Students will understand how genes move.
What is a gene pool?
total genetic information available to a population
Where would the gene pool of humans be found?
everywhere humans are found. Humans have the capacity to have reproductive success with other humans regardless of where they live.
If you had the following information: What would the allele frequency be of the dominant allele? B=brown b=blue 22 = BB 58=Bb 29=bb
102/218 or .46 or 46%
If you had the following information: What would the phenotype frequency be for Brown coloration? B=brown b=blue 22=BB 58=Bb 29=bb
80/109 or .73 or 73%
If you had the following information: What would the genotype frequency be for bb? B=brown b=blue 22=BB 58=Bb 29=bb
29/109 or .27 or 27%
How would a small populations data on phenotype frequencies be compared to larger populations>
They will be unexpectedly high or low. The gene pool for small populations will be much smaller than a large population.
Allele frequency changes over time is an indication of
Evolution
Why did the rock pocket mouse allele, genotype, and phenotype frequencies change?
the environment(lava) changed.
The phenotype of the rock pocket mouse changed because of a
random mutation, that made them more fit for their environment.
