You are studying snails and find that individuals have shells that coil either to the right or to the left. Which of the following is/are the most plausible explanation(s) for this variation?
A) Different alleles at a single locus produce the different phenotypes.
B) Individuals are genetically identical, but certain environmental conditions trigger the production of each coil type.
C) This is a quantitative trait, meaning that many loci contribute to the phenotypic differences.
D) a and b
E) a, b, and c
Quantitative Trait
A measurable phenotype that depends on the cumulative actions of many genes and the environment.
Alleles
Alternative versions of a gene that produce distinguishable phenotypic effects.
Environmental Conditions
Various factors or circumstances in the environment that can affect living organisms, including temperature, humidity, and pollution levels.
