Robertsonian translocation occurs of 2 acrocentric chromosomes with no problems for the person carrying it in balanced form. In an unbalanced form, it produces chromosome imbalance leads to mental disorder or malformations.

In this translocation p arm or long arm join with other chromosome's long arm, carrier is normal due to the presence of 2 copies of all chromosome arms so there will be all the copies of essential genes.

Research how the body uses feedback mechanism to decrease the heart rate after exercise. what specifically happens in the body t
maw [93]
<span>A negative feedback loop works by adjusting an output, such as heart rate, in response to a change in input, such as blood pressure. A basic loop consists of a receptor, a control center and an effector. If you are at rest and your blood pressure increases, pressure receptors in your carotid arteries detect this change in input and send nerve impulses to the medulla of your brain, or control center. This signals the brain to reduce nerve impulses that stimulate your heart muscle, an effector, to contract. Your heart contracts more slowly and your output, or heart rate decreases, causing your blood pressure to decrease to within target levels.</span>
