A population of snails is experiencing disruptive selection in terms of their shell patterns. Which statement is most likely true about the population? Two different shell patterns are increasing in frequency, while the most common pattern is decreasing. The frequency of the most common shell pattern is becoming higher than all other patterns. The frequency of a new shell pattern is becoming higher than all other patterns. Two different patterns are combining into one very common pattern.

Answer;

Two different shell patterns are increasing in frequency, while the most common pattern is decreasing (CA).

The statement that is most likely true about the population is that two different shell patterns are increasing in frequency, while most common pattern is decreasing.

Explanation;

Disruptive selection involves changes in population genetics such that the extreme values of a trait are favored over the intermediate values.

Disruptive selection often drives speciation.

It may also occur when environmental changes favor individuals on either end of the phenotypic spectrum.

Two different shell patterns are increasing in frequency, while the most common pattern is decreasing. The two extreme shell patterns increase in frequency while the intermediate one does not
