List the four (4) major groups for the antidepressant medications and the prototype of each one.  what are the major differences between the four (4) classes?

The 4 major groups of Antidepressants are:

1.       Selective serotonin reuptake inhibitors may comfort depression by aggregating intensities of serotonin in the brain.  Examples of this are: Citalopram, Escitalopram, Paroxetine, Fluoxetine, Fluvoxamine, and Sertraline.

2.       Atypical Antidepressants aims other neurotransmitters either alone or in accumulation to serotonin. Examples of this are: Bupropion, Mirtazapine, and Trazodone.

3.       Tricyclic Antidepressants upsurge levels of norepinephrine and serotonin. Examples of this are: Amitriptyline, Amoxapine, Desipramine, Doxepin, Imipramine, Nortriptyline, Protriptyline, and Trimipramine.

4.       Monoamine oxidase inhibitor eliminates the neurotransmitters from the brain. Examples of this are: Rasagiline, Selegiline, Isocarboxazid, Phenelzine, and Tranylcypromine.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
