It can be said that a genotype can be considered to be a set of genes that an organism carries with itself. On the other hand, an organism’s phenotype can include all the observable characteristics which can be influenced by both genotype and the environment. It can be said that the subsequent combination of alleles that the individual possess for their specific gene can be called the genotype, for example- a gene that encodes the eye color. Example of phenotype can be the environmental and lifestyle factors (Campbell, 2019).
