Horses can be cremello (light cream), chestnut (brown), or palomino (gold with white manes and tails). Oddly, breeders have been unable to make a pure-breeding palomino strain. In crosses, breeders see the following results: cremello X palomino: 1/2 cremello, 1/2 palomino palomino X palomino: 1/4 chestnut, 1/4 cremelo, 1/2 palomino chestnut X palomino: 1/2 chestnut, 1/2 palomino How many genes are involved in these results

There is only one gene involved in these results.

Explanation:        

You will find the complete answer and explanation in the attached file due to technical problems.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

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.
