Indicate which of the statements below is True or False. Enter 1 for True and 2 for False. Question 2 options: Evolution can be described as changes in the proportion of variable traits (including different alleles) within a population over generations. Morphological variation between individuals is almost always correlated with genetic variation, ie. those individuals that differ in phenotype also differ in genotype. Variation in morphological traits may be due to genetic or environmental factors, but both causes of variation can be inherited and be subject to evolutionary change. Phenotypic plasticity is the term used to describe plastic, or variable, responses by individuals with the same genotype under differing environmental conditions.
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.
