6. Design an Experiment: As a student researcher, you have been tasked with conducting an experiment to test three food products for the presence of a protein (the chemical composition of substance A, B, and C being unknown). Design an experimental procedure which would allow you to determine which of the three unknown substances contains protein. Be sure to include: which test you will employ, what substance will act as your positive control, which will act as your negative control, and what color change will indicate the presence or absence of a protein.

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
