In rabbits, full coat color (c) is the dominant trait. a second allele, chinchilla (cch) is recessive to full coat color. himalayan coat color (ch) is recessive to chinchilla and full coat colors, and albino (c) is recessive to all coat colors. if a heterozygous chinchilla rabbit mates with a homozygous himalayan rabbit, what is the expected phenotypic ratio in their offspring?

50% Chinchilla y 50% Himalaya

Explanation:

In this case one parent is chinchilla as dominant trait, plus another recesive trait, which can be himalaya or albino. The offspring will be 50% Chinchilla y 50% Himalaya, because the trait himalaya is recessive to Chinchilla, and albino is recessive to himalaya.

Cchch (Chinchilla+himalaya or albino ) x chch (himalaya) :

1- Cchch Chinchilla

1- Cchch Chinchilla

1- chch himalaya

1- chch himalaya

the answer to your question is b

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.
