Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Answer:
Tyrosine derived neurotransmitters
Explanation:
These neurotransmitters are produced as a result of the conversion of tyrosine when not incorporated into proteins or energy production is converted to catecholamines.
These catecholamines includes dopamine, norepinephrine, and epinephrine.
All these three catecholamines produce various effects in numerous locations in the body acting either as a neurotransmitter or as a hormone
