Polygenic inheritance can be explained as Mendelian inheritance at many loci, resulting in a trait which is normally-distributed. If n is the number of involved loci, then the coefficients of the binomial expansion of (a + b) 2n will give the frequency of distribution of all n allele combinations.
Once the pacemaker is implanted, the leads carry signals back from the heart. The pulse generator reads these signals and the batteries send electrical impulses to the heart to help pace it. Most pacemakers can sense the heart's rhythm and turn themselves off when the heartbeat is above a certain level. They will turn on again when the heartbeat is too slow. These types of pacemakers are called demand pacemakers.
Customer Question. My 2000 ford taurus turned off as I was driving like someone turned off the key, then it won''t even turn over at the starter.I can jumper the starter solenoid and the engine turns over but won''t start. I''ve tested and found that there is no ground on the starter Relay in the under the hood fuse box.When I place a ground on the starter relay and have someone turn the key the starter turns over but there is no fire to the plugs.ustomer Question.
