The scar tissue that occurs between the layers of the pericardium becomes rigid and constrictive from scar tissue in constrictive pericarditis. What is a physiologic sign of constrictive pericarditis

Kussmaul's sign

Explanation:

Due to constrictive pericarditis, the pericardium becomes rigid. As a consequence, the filling of the right ventricle during diastole does not happen correctly. The incomplete filling and the constrictive walls make the blood flow back to the veins, which leads to increase pressure in the jugular vein. This malfunction on the jugular pressure due to heart disease is known as Kussmaul's sign.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
