A research study looked at variations in snail populations in urban areas compared to natural ecosystems outside of the urban development. Urban areas tend to be be warmer, trapping more solar energy and reflecting less light back out of the atmosphere. The
study found that brown snails were more commonly found in the natural ecosystem while yellow banded snails were found in the
urban, developed areas. Which statement best describes the distribution in the phenotypes for the snails in this scenario?
es 0)
A)
The variations in the snail populations are random and unrelated to the
locations.
B)
The variation in the snail population is due to sexual reproduction of the
snails in the urban development and asexual reproduction of the snails in
the natural ecosystem.
The variation in the snail population is due to mutations while the
distribution of colors in the population is due to genetic drift. The location Eliminate
of the colors a random process.
D)
The variation in the snail populations is due to mutations while the
distribution of colors in the population is due to the changes in
temperature in the two areas. Lighter colored snails survive with greater
frequency in the warmer urban development.
