Question

An organism that has been observed in the Atacama Desert undergoes mutations in its genome. The trait caused by the mutation is beneficial to the species' survival. Complete the model to show the process of natural selection during the third, fourth, and fifth generations.

Answer 1

This presnt a descriptive model depicting the process of natural selection over the third, fourth, and fifth generations for the organism in the Atacama Desert:

Third Generation:

Mutation occurs, creating a beneficial trait for survival.

Organisms with the beneficial trait have higher chances of survival.

They pass the beneficial trait to their offspring.

Fourth Generation:

More organisms in the population inherit the beneficial trait.

The population becomes dominated by individuals with the advantageous trait.

Those with the trait have increased survival and reproduction rates.

Fifth Generation:

The majority of the population now possesses the beneficial trait.

The advantageous trait becomes more widespread and common.

The population as a whole is better adapted to the Atacama Desert environment due to the beneficial trait.

This model illustrates how, over generations, a beneficial trait resulting from a mutation becomes more prevalent in a population through natural selection, contributing to the species' adaptation to its environment.

Answer 2

Answer and Explanation:

The organism that developed the mutation will multiply, passing this mutation on to its descendants. These descendants will multiply and pass this mutation on to their descendants who will continue to develop organisms with this mutation. As the generations advance, individuals with this mutation will become more and more numerous, since the mutation allows them to survive in the desert. Those who do not have the mutation, however, will multiply less and less, since they started to die, due to the pressure of the environment and natural selection. In this case, we can confirm that from the third to the fifth generation, the entire population of this organism will be composed of individuals with the mutation.
