Question

You are studying a population of pea plants which flower colors ranging from white to dark pink. You selected only those plants with the darkest pink flowers to use in cross-pollination. Once you plant the seeds and grow your new generation of pea plants, what would you expect to see

Answer 1

The question is incomplete as it does not have the options which are:

You would see disruptive selection.

The relative numbers of flower colors would remain unchanged.

The relative numbers of white flowers would increase.

Your results would show directional selection.

Answer:

Your results would show directional selection

Explanation:

In the given question, the pea plants produce a range of flower color from white to pink and then dark pink. If we will grow the plants with dark pink flowers than the plants in that area will have dark pink flowers.

In evolutionary terms, this can be suggested that the growing the plants with by humans is a natural force that is favoring the extreme color of the flower which is dark pink and natural selection will be observed.

In this scenario, since the dark pink color is the extreme color which is favored by the humans to grow therefore the directional way of natural selection is acting which is characterized by the favor of only one extreme phenotype.

Thus, the selected option is correct.
