The shorthorn breed of cattle carries the gene ww for white coat color, and the gene ww for red coat color. when a white individual is bred with a red individual the hybrid result is a roan ww that has a mixture of red and white coat color. part a what is the dominance pattern for the roan color? part b how does the roan color come about?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
