A lod score of 3 or higher is usually considered convincing evidence for linkage.

A lod score of -2 or lower is usually considered convincing evidence for independent assortment.

Atrial systole 

Preceded by the depolarization of the atria

Contraction of the atrium causes an increase in atrial pressure.

#Unit 7. System Physiology – Animal

Atrial systole

The P wave is caused by spread of depolarization through the atria and is followed by atrial contraction.

Atrial systole 

Increase in atrial pressure is reflected back to the veins, it appears on the venous pulse record as the a wave.

Atrial systole 

ventricle is relaxed, & because the AV valve is open, the ventricle is filling with blood from the atrium, even prior to atrial systole.
