The United Nations predicts that the human global population is most likely to stabilize at 9 billion within the next 100 years. If the population level remains at this level for the next 10 KY, what would you predict about the strength of selection required to overcome the effects of genetic drift, compared to today’s values? A. It would be the same. B. The future strength of selection would be greater than today’s values. C. Not enough information. D. Today’s strength of selection would be greater than in the future
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.
