Question

A new mutant population of fruit flies has been discovered with defects in the checkpoint of the cell cycle that makes sure that DNA has finished copying. Predict what will happen over time in this population.

(4 points)

Answer 1

With defects in the cell cycle checkpoint that ensures DNA has finished copying, this new mutant population of fruit flies is likely to experience an increase in errors during cell division. This can lead to a higher rate of mutations and genetic abnormalities in the offspring of these fruit flies. Over time, this population may experience reduced fitness and potentially increased rates of diseases or abnormalities. The population may also become more susceptible to environmental stressors due to the accumulation of genetic mutations. Additionally, with the potential for increased genetic diversity in the population, there may be some individuals who exhibit advantageous traits that allow them to survive and reproduce more successfully, leading to potential evolution or adaptation within the population.
