In terms of human evolution, the sagittal crest was usually more pronounced and larger in older and robust species compared to younger or gracile species. 
Hope that helped! :)
        
             
        
        
        
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. 
        
             
        
        
        
Answer:
If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.
Explanation:
This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.
The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
