You notice a change in once species of the fish population in a large pond you are studying. The initial speicies population had mostly Speckled (black and white) fish with smaller but equal numbers of pure Black fish or pure White fish. You counted 50 Speckled fish, 25 pure White fish, and 25 pure Black fish in the population six months ago. All alleles are equally dominant
What are the gene frequencies for the Black allele and the White allele in this original popluation? What kind of gene expression do you think is occuring in the Speckled fish?
Since your last count, black gravel was spread on the bottom of the pond. you recently showed 49 pure Black fish, 42 Speckled fish, and only 9 White fish.
What are the new gene frequencies for this popluation?
What do you think is happening to all the species of fish in the pond? Will the White allele ever disappear?
