When trees were light in color, the light-colored moths increased in frequency. When the trees were dark in color, the dark colored moths increased in frequency. No individual moths changed colors.
Why do moths change colors?
The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do.
Why did the allele frequency of white colored moths decrease?
Oh my bad by population I meant the allele frequency of white coloured moths decreased because there weren't as many white moths that were able to place the white allele color into the gene pool because many did not survive to reproduce. That's so cool! You must be Canadian as well?
What happened to the black colored moths?
I had an answer similar to yours but following the same idea that the black colored moths that were able to be camouflaged on the soot that covered the trees survived and the white ones died and were not able to reproduce.
What is the difference between white moths and black moths?
Black moths were able to reproduce and live while white moths were not able to reproduce or there were not as many white moths reproducing meaning the population of white moths were decreasing while the population of black moths increased. I agree with your answer.
What was causing the change in the color of the moths?
Genetic Changes Moths passed their color to the next generation. Eggs from light moths developed into light moths and dark moth eggs turned to dark adults. The dark color was caused by a mutation in the DNA of a single moth, and the mutated gene had been passed to all its offspring.
What caused the change in the moth population?
When the environment changed, due to pollution, the moth population shifted because light-colored moths became easier to see so they were eaten more often. Organisms that survive have a better chance of reproducing so the population continues to grow. Human actions affect other populations.
How does this help explain the change in the colors of the moth population?
How does this help explain the change in the colors of the moth population shown in Model 2? Because the light-colored moths were easier to see on the dark surfaces, they were easier prey and could not have as many offspring as the dark-colored moths that were harder to see and could sur- vive longer.
What is the best explanation for the moth population changing over time?
Natural selection was the best explanation for the change in the moth population over time.
How the color of the moths increases or decreases their chances of survival?
As the trees darkened with soot, the light-colored moths were easier to see. They were eaten by birds more and more, while the rare dark colored moths blended in better on the darker trees. This made the dark colored moths have a higher survival rate.
Which change in the environment led to a change in the population of peppered moths during the 1800s?
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.
Can moths change colors?
Peppered moths are so common that there's probably one near your house right now—and thanks to transposon mutations and natural selection, the moths in your neighborhood could further change color as industrialization morphs their environment.
Why were the dark gray peppered moths able to survive better once the trees were colored in soot?
This color was advantageous because the gray peppered moths were camouflaged when they stayed on gray- colored areas on the sides of trees in their habitat. Predators, which were mostly birds, could not see the moths on the trees because the color of the moths blended in with the color of the trees.
Why do the dark colored moths have a disadvantage?
To have a light body, the moth has to have both alleles for light body color. Dark moths were at a distinct disadvantage, however, due to their increased vulnerability to bird predation.
Which of the following statements best describes what will most likely occur to the moth populations in the image below?
Which of the following statements best describes what will most likely occur to the moth populations in the image below? The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.
What will happen to the populations of light and dark moths on light trees?
The dark moths are highly visible to predators against the light tree, but the light are nearly invisible to predators. So, it is likely that more dark moths will be captured by the predators, causing the population of light moths to decrease.
Why did the dark colored peppered moths survive better during the Industrial Revolution?
Light-colored peppered moths were not able to blend in with this environment making them easy to spot to predators compared to their dark colored kins. Due to this, the darker-colored peppered moths survived better and had the opportunity to proliferate considerably more than those light-colored ones.
What was the change to the peppered moth population that began appearing in 1848?
They were losing their selective advantage to the dark moths, which, against the trees' dark bark background, were less visible to birds. In 1848, the dark moths comprised 1% of the population and by 1959 they represented ~90% of the population. So, in 100 years the frequency of dark moths increased by 1000 fold!
How did the populations of moths change in the ten year period represented on your graph?
The number of light moths (red) decreased over the 10 year period, and the number of dark moths increased. These moths live in an area where the tree bark is dark.
How did the Industrial Revolution affect the peppered moth?
Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat.
Why do moths change color?
This is how I answered the question: Because the best-hidden moths survived and reproduced, passing on their colors to their offspring. Moths can't change colors, they just do not have that ability. The dark moths better adapted to their environment so they reproduced more. This caused the changes observed in the moth population. The dark trait was selected for and the light trait was selected against.
Do moths change color in moth pop?
I agree with your answer. So yes , the changes observed in the moth pop resulted because the best-hidden moths survived and reproduced, passing on their colors to their offspring. 2. level 2. Deost8003.
