Roscroot (Sedum integrifohum) is an herbaccous plant species that is found on limestone cliffs in southeastern Minnesota and westem New York. and on rocks slopes at high elevations (3,000 m. or - 10.000 At) in Colorado. In Minnesota and New York. the plants are sprawling and have -drooping leaves, whereas in Colorado the plants are erect and hold their caves upright. a. Briefly describe a study that vou could do in order to determine if the differences in plant morphology observed in these populations of roscroot are genetically based or due to environmental factors and describe the results that would allow vou to conclude that it is heritable. (Do not provide a detailed expenmental design.)

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.
