A mutation that stops the production of acid (H+) in the stomach such that no acid is ever produced would most likely lead to: (hint: draw out the diagram):

a build-up of pepsin in the stomach

inadequate mucus production from the lining of the stomach

a build-up of pepsinogen in the stomach

an ulcer (injury in the stomach)

a failure to produce pepsinogen

Answer #1

Right answer is:

a build up of pepsinogen in the stomach.

Explanation:

HCl is secreted by the pariental or oxyntic cells pf the atomach. And peptic or chief cell secretes pepsinogen from the stomach. HCl activates the pepsinogen and convert it into pepsin.

That's why when HCl or H+ is not produced in the stomach, then pepsinogen is not converted into pepsin. In this way pepsin is accumulated in the stomach.

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
