Scenario 2: A scientist is studying a population of lizards in a local pond. The lizards are normally a murky brown color and blend in with the water and banks of the pond to avoid predators. Recently the scientist has noticed lizards that are born white instead of the normal brown color. He does genetic testing on both types of lizards and determines that the brown coloring should be the only color option for that type of lizard. Select the best explanation for the albino lizards. A Brown color is recessive to white. B The DNA mutated to change the color brown to white. Someone painted the lizards white.
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.
