recessive allele frequency
typica al
carbonaria 14, 20
if 10 typica moths and 90 carbonaria moths were released into a polluted forest what would happen over several generations?
check all that apply
the typica moth population would decline.
the carbonaria moth population would have a reproductive advantage in the polluted forest.
the carbonaria moth would be easily spotted by predators on the dark polluted trees.
the carbonaria moth population would decline.
the recessive allele frequency would decrease each generation.
the recessive allele frequency would eventually reach zero.

Explanation:

In a polluted forest, the dark - colored Carbonaria moths have a camouflage advantage over the light - colored Typica moths. This gives the Carbonaria moths a reproductive advantage as they are less likely to be preyed upon. As a result, the Typica moth population would decline, and the Carbonaria moth population would increase. The recessive allele frequency (associated with the Typica form) would decrease over generations.

Answer:

• The Typica moth population would decline.
• The Carbonaria moth population would have a reproductive advantage in the polluted forest.
• The Carbonaria moth would be less likely to be spotted by predators on the dark - polluted trees.
• The recessive allele frequency would decrease each generation.
