Molly's natural hair color is wn but she has had it dyed blonde. molly changed her _____. genotype phenotype chromosomes genetic heritage

The correct answer is - phenotype.The phenotype represents the composition of an organism's characteristics and traits that can be observed (the physical ones), such as the physiological and biochemical properties and traits, behavior, development, morphology... In this case we have an artificial change of the physical appearance, when the natural color of the individual's hair is changed, thus changing its physiological property/trait, which falls into the category of phenotype change.
