That would be the nuclear membrane. Eukaryotic cells have a nucleus that encases their DNA, so it stays safer than it would in a prokaryotic cell.
There are 2 functions for cell surface markers. The first is to recognize the outside cell. The second is to allow the cell to bind to substances outside the cell.
Cell surface markers are proteins expressed on the surface of cells that often conveniently serve as markers of specific cell types. There are different types of cell surface markers. These markers are vital for the human body to function. These markers also vitally affect the functions of other biological systems of other organisms and creatures such as animals.
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.
The cell theory of course had an important impact on later scientific discoveries as many different hypothesis and scientific discoveries were derived and concluded with the help of basics from this theory.
