)The figure below shows the shell length in two random, and representative samples of mussels from the same species. The samples were obtained from the same population but two years apart. Knowing that this species of mussel can live for over a decade, which statement is consistent with the data? The population experiences random genetic drift The population experienced purifying selection The population evolved to be shorter The population is undergoing inbreeding depression The population experienced directional selection
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.
