How can a change in genotype affect the phenotype

Roughly, the definition of 'genotype' is a description of genetic characteristics or makeup. Phenotype can be described as the resulting physical characteristics subsequent to genotype. This means that differences in genetic makeup could greatly influence how something, such as an embryo, develops.

Comment: I use a memory aid for this ind of thing, as I easily get them mixed up. Simply use the two letters of each word. Genotype --> genetic, and phenotype--> physical. Hope I answered your question.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
