The VH is different from the V₁ in what way? VH is heavier. VH uses an additional gene segment. VH cannot exist independently. The VH gene segments do not need to be joined.
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.
One component of the antibody molecule that helps with its antigen-binding selectivity is the Variable Heavy (VH) region.
The "heavy chains" of the antibody, one of the two identical protein chains that comprise the antibody structure, contain VH regions.
V (Variable) and D (Diversity) gene segments are among the gene segments that are recombined to form VH sections, which are unique sequences that dictate the specificity of an antibody against a certain antigen.
Another component of the antibody molecule that aids in antigen binding and specificity is the Variable Light (VL) region.
"Light chains" are the other group of identical protein chains in the antibody structure, and here is where VL regions are located in the antibody.
