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.

inheritance patterns
Inheritance or heredity is passing-on one trait form the parents to the progeny by either asexual or sexual reproduction. Genetic information is passed from one generation to another via DNA.
Inheritance patterns differ from genes on sex chromosomes(X and Y) to genes located on autosomes(1 to 22). The reason is that female carries two X chromosomes(XX) so the female would carry two copies of each X-linked genes and no Y-linked genes, whereas males carry one X and one Y chromosome(XY) so would carry only one copy of each X and Y- linked genes.
