Here is the complete answer choices for the last question
C. A conservation group releases several new birds to the area, to repopulate the birds. The new birds are predominantly brown feathered.
natural selection
genetic drift
gene flow
frequency of brown feather alleles increase
allele frequencies change, but not predictably
frequency of yellow feather alleles increase
allele frequencies stay the same
What mechanism is in work here?natural selection
genetic drift
gene flow
What is the effect on the gene pool?frequency of brown feather alleles increase
allele frequencies change, but not predictably
frequency of yellow feather alleles increase
allele frequencies stay the same
Populations evolve for many reasons. Suppose there is feathers, and the allele for the brown feathers is dominant. The frequencies for the two alleles in the population are approximately equal For each event or condition described below, answer the following questions. a small population of birds that have either brown chest feathers or yellow chest What mechanism? Identify whether the event is natural selection, genetic drift, or gene flow . Gene pool effect. Select the best description of how the allele frequencies change A. Birds with yellow chest feathers attract more mates and leave more offspring What mechanism is in work here? O natural selection genetic drift O gene flow What is the effect on the gene pool? O frequency of brown feather alleles increase allele frequencies change, but not predictably O frequency of yellow feather alleles increase allele frequencies stay the same B. A hurricane kills many birds at random. What mechanism is in work here? O natural selection genetic drift O gene flow What is the effect on the gene pool? O frequency of brown feather alleles increase allele frequencies change, but not predictably O frequency of yellow feather alleles increase allele frequencies stay the same C. A conservation group releases several new birds to the area, to repopulate the birds. The new birds are predominantly brown feathered. What mechanism is in work here? O natural selection genetic drift gene flow What is the effect on the gene pool? O frequency of brown feather alleles increaseExplanation / Answer
Genetic flow
Frequancy of brown feather bird increases
Note - the change in allele frequancy lead to increase in thier number in population . These changes bought out by migration of one population into other is gene flow .
