The distribution of shell heights in a population of snails changed over time, as shown. Distribution of Shell Heights Initial Final 100 100 75 75 Number of Shells 50 Number of Shells 50 25 25 0 55 10 15 10 15 Shell Height (mm)Shel Height (mm) Which of the following best explains what happened to the genetic diversity of this snail population in regard to shell height ? (1 point) Genetic diversity stayed the same because of equal birth and death rates. Genetic diversity decreased because of selection pressure. Genetic diversity increased because of changes in food sources.
Based on the information given, it is not possible to determine the change in genetic diversity of the snail population in regard to shell height. The distribution of shell heights only provides information about the number of shells at different heights, but does not provide any information about the genetic diversity of the population.
