Can more than one different kind of selection (say, stabilizing and disruptive) happen at the same time?
Homework Answers
No at one time only one type of selection can happen. Because in case of stabilization selection the stabilized characters are selected by nature. In case of stabilization selection the mean or the avarage characters become more favourable in the environment. For ex human baby body weight at their birth time have an avarage value. In case of disruptive selection the extreme characters are selected by nature. Here we can see nature select two different types of characters one is avarage type and other is extreme type, so it can be said that these two type of selection can not occur at the same time.
Here the 1st graph is for stabilization selection and 2nd is for disruptive selection.

One selective force (or mixture of forces) limits the largest viable birth weight of a human baby, while another selective force limits the smallest viable birth weight of a baby. This is called .............. natural selection. a. Artificial b. Fictional c. Directional d. Disruptive e. Stabilizing A population splits into two rather different populations. The two phenotypic extremes of the original population are favored over the more common central phenotype of the original population. This is called ............ natural selection....
