Genetically identical roundworms are raised in two different environments.In the warmer environment, the worms are shorter than they are in the cooler one.What can we infer from this observation?
A) Different genotypes can have different alleles.
B) Different genotypes can produce the same phenotype.
C) Different phenotypes can arise from the same genotype.
D) Dominance complicates the study of the genetic basis of evolution.
E) A heritable trait is a characteristic that is at least partially determined by the organism's genes.

Question

Quizplus · Accepted Answer

The fact that genetically identical roundworms raised in different environments have different phenotypes (shorter in warmer environment) implies that different phenotypes can arise from the same genotype. This could be due to the expression of certain genes being influenced by environmental factors, which can result in different physical characteristics even in genetically identical individuals.
