In some types of wheat, color is caused by two sets of genes. both dominant genes a and e are needed for red color. white results from both recessive genes in the homozygous state (aaee). other combinations will produce brown wheat grains. a strain with the genotype aaee is crossed with a strain having the genotype aaee. what will be the frequency of red offspring?

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.
