Answer:

G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.

The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.

How does the control of gene expression lead to differentiation of cell function in multicellular eukaryotes?
Sergeeva-Olga [200]
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.

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.
