The answer to that is, Chlorine
Genes organized on
chromosomes carry the information that controls the functions of the cell. Each gene contains a particular set of code for a particular molecule or protein for a specific function.
Well, there is only one realistic answer. Option One is when you take the DNA of two different people or creatures and combine them into one organism. Cloning wouldn't prove anything here, "hybridization" is weird - but it doesn't have anything to do with the situation. So only only remaining option is DNA Profiling - also known as DNA Mapping, which shows the DNA structure and order that can be seen the same way in siblings (slightly different of course but it is still the right answer).
Assuming the white phenotype is recessive. white: gg
I think the gray mouse is Gg because the offspring were pretty equally distributed in terms of color. See the punnet square below.
g g
G| Gg Gg
g| gg gg
If the Gray phenotype is recessive, then gray: ww but only if white is Ww because its about 50% chance for both.
