Give typing answer with explanation and conclusion 1) A population of HIV viruses exposed to any single antiretroviral medication typically evolves resistance to this medication within a year or two. In contrast, populations of humans exposed to HIV for many years have not yet evolved significant resistance to HIV infection. Which of the following reasons may explain why evolution has been so much more rapid in HIV populations than in human populations? a) Humans have much longer generation times. b) Humans have reverse transcriptases that are less error prone.
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.
