Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
Dr. Alvarez is doing research on the subfield of psychology called the behavioral neuroscience. Scientists from the field study the biological foundation of human behavioral characteristics. These scientists are trying to find out what physiological processes and anatomical structures are involved in certain aspects of human behavior.
Selective selection,since being smaller is an advantage the rabbits got smaller similar to evolution
Not sure if I'm correct but my best guess is the cell membrane seeing as it surrounds the cell itself and is responsible for allowing certain molecules to diffuse in or out of the cell. Good Luck! :)
