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.
Explain the role of hairpins and hairpin resolution in generating diversity.
The hairpin are necessary beccause they are the secondary structure of RNA. They are responsible for guiding the folding of RNA and are used to determine the interactions which are there in a ribozyme. They also play a major role in the protection of messenger RNA from degradation. They are used as the substrate for enzymatic reactions.
The hairpin in DNA could also form a loop but are mostly observed in the RNA.
