Artificial Selection- Concept

JoVE 10555

Natural Selection and Adaptive Evolution

In natural settings, adaptive evolution takes place by natural selection, a process in which differences in traits lead to differences in survival and reproductive success between individuals. This happens because individuals with certain phenotypes have a higher probability of survival and/or produce more surviving offspring than individuals with …

Artificial Selection - Student Protocol

JoVE 10556

Observing Artificial Selection in Plants
To begin the experiment, collect five two-week old grown plants from the generation one population that appear healthy. Note: Plants should appear green, not wilted, and not have damaged leaves. Experimental Hypothesis: The experimental hypothesis for this lab might be that the number of lead trichomes varies…

Artificial Selection - Prep Student

JoVE 10554

Observing Artificial Selection in Plants
Two weeks before beginning the pollination experiments, collect a sufficient amount of small pots with a drainage hole in the bottom of each pot.
Fill each pot about halfway with moist potting soil. NOTE: It is recommended to use a minimum of 50 plants for generation one. It is standard practice to list…

Reconstitution of Membrane Proteins

JoVE 5693

Reconstitution is the process of returning an isolated biomolecule to its original form or function. This is particularly useful for studying membrane proteins, which enable important cellular functions and affect the behavior of nearby lipids. To study the function of purified membrane proteins in situ, they must be reconstituted by integrating them into an artificial lipid membrane.
