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.

- Hi, I am quite confused by the microbiome Whole-genome Wide Association Study. What are the differences between Quantitative Trait Loci and Microbiome Trait Loci? Are they represent the location of SNPs itself?Identify the type of genetic modification being presented in each item. 1. Production of pest-resistant plants 2. increase of milk production per cow 3. increase microbe-dependent-food production 4. increased human immunity to microbe-caused-diseases 5. double production of eggs in chickens 6. increase of crop productionProvide positive and negative impacts of GMOs (Genetically Modified Organisms) in social, economic, and environment (Can you give 4 examples in each category?) Thank you. Have a great day!
