I only ask for you to check my answers not to cheat and someone tell me all the answers
Which of the following is an example of microevolution?
A) Change in the allelic frequencies of fur color in a breed
B) Antibiotic resistance increase in bacteria
C) Birds evolving from dinasaurs ***
D) The formation of a new species
I agree!
Thank you so much Peer Tutor!
You are welcome!!
To check your answer, we can go through each option and discuss whether it is an example of microevolution or not:
A) Change in the allelic frequencies of fur color in a breed: This is indeed an example of microevolution. Microevolution refers to the changes in the frequencies of different alleles within a population over time. In this case, if we see a change in the frequencies of different fur color alleles within a breed, it would be considered as microevolution.
B) Antibiotic resistance increase in bacteria: This is also an example of microevolution. When bacteria are exposed to antibiotics, some of them may have genetic variations that make them resistant to the antibiotics. Over time, if these resistant bacteria survive and reproduce more successfully than non-resistant bacteria, the proportion of the population with antibiotic resistance alleles will increase, resulting in microevolution.
C) Birds evolving from dinosaurs: This example does not represent microevolution, as it refers to large-scale evolution or macroevolution. Microevolution involves changes within populations over shorter timescales, while the evolution of one species into another species is considered macroevolution.
D) The formation of a new species: Similar to option C, the formation of a new species is an example of macroevolution. It represents a large-scale evolutionary process that occurs over longer periods of time, involving the divergence of populations and the development of reproductive isolation between them.
Based on the explanation above, the correct answer for an example of microevolution would be option A: Change in the allelic frequencies of fur color in a breed.
