Crossing over is a complex mechanism which allows the exchange of the DNA sequence during meiosis.
Crossing over serves many purposes:
1. form genetically different daughter cells from parents.

The crossing over does not take place in the mitosis type of cell division which produces genetically similar daughter cells.
The mineral substances that are normally found in the blood, such as sodium and potassium, are known as Electrolytes.
<h3>Who are electrolytes?</h3>
Electrolytes are minerals that carry an electrical charge when they are dissolved in a liquid such as blood. Blood electrolytes – sodium, potassium, chloride and bicarbonate – help regulate nerve and muscle function and maintain an acid-base balance.
Major Electrolytes are Sodium, potassium, calcium, phosphate and magnesium are the electrolytes involved in salt balance disorders. In addition, the concentration of chloride and bicarbonate is commonly measured.
