Aliens from planet moby have three alleles for skin color: r (red) w(white) and b (blue). if all of these alleles are codominant and aliens on planet moby can only inherit two alleles for a gene, what are the six possible genotypes for skin color in these aliens?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
