Answer the following introductory questions: 1. What type of selection (natural, artificial, genetically engineered) best represents the process of selective breeding that has led to plants with drastically modified traits (i.e. kohlrabi, kale, broccoli, Brussels sprouts, cabbage and cauliflower). Who is the responsible (the "agent" of change) for the desired traits?

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.
