Question:
A population of organisms is represented by three black marbles and three gray marbles. The gray organisms have a beneficial genetic mutation. Draw a model that shows natural selection over three generations of these organisms
Answer:
lThe population will suffer Directional selection. In the attached files you will find the drawing of the model.
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. Among other types of natural selection, we can find the directional selection.
Directional selection increases in the proportion of individuals with an extreme phenotypic trait, in this case, the color of the organisms. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
Directional selection leads to the fixation of the beneficial allele and the consequent loss of the other one. In this case, for example, the gray suffered a beneficial mutation, and after three generations the allele codifying for this mutation shows an increase in its frequency, approaching fixation.
