He also has normal vision reason why he is X-NY and X-N which represents the X chromosome with the dominant N allele for normal vision. The woman is color blind and hence a homozygous recessive X-nX-n and of normal height.
Autosomal dominant helps to alleles harbored by any chromosome other than the sexual pair that show complete dominance over the recessive ones. Other diseases such as Huntington's disease, are autosomal dominant.

The main signal in small intestine for pancreatic bicarbonate ion secretion is Secretin.
When food from the stomach with acidic medium enters duodenum(first part of small intestine) it stimulates the lining of duodenum cells to release the hormone secretin.
This hormone travels via bloodstream to pancreas and stimulate to it to release bicarbonate ions.Now these ions enter duodenum and neutralise the acidic medium.
This results in the optimum pH for the enzymatic action to take place thereby promoting final digestion of protein.
