Imagine that some lizards from both islands are brought to a laboratory and lizards from each population are separately bred for a generation. The offspring resemble their parents (i.e. they look like lizards from their home island). Does this support or contradict the idea that evolution has occurred? Group of answer choices a. support because it implies that a genetic change has occurred b. contradict because the lizards were removed from the islands c. support because the phenotype matches the environment d. contradict because the environment is different in the lab e. support because it is a major change in phenotype
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.
