Suppose you had 50 bean seeds. You let 25 of them grow for 7 day (Group A). You keep the other 25 seeds in a bag (Group B). You then carefully dry out all of the water from the seeds/plants in both groups. Which one should weigh the most? Why?
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.

The seeds carry the ability to stay viable for a long period of time. The ability of the seeds can vary from species to species. Some of the species have seeds that can grow into plants even after years.
