Mumz [18]

to understand what the result of these crosses would be like, we need to know what is gene

The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.

Genes can be classified into:

Dominant genes: assume the specific characteristic in the offspring;
Recessive genes: manifests itself in the absence of the dominant gene;
Structural genes: are those that contain the information that will determine the structure of living beings;
Operator gene: acts on the functioning of other genes;
Regulatory gene: responsible for controlling the synthesis and transcription of other genes.

in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.

with this information we can say that a white and short plant, when crossed with a plant for both traits, has 60% of this plant being with expression of the dominant genes and 40% of being with expression of the recessive gene.

Aloiza [94]

The term Neurotransmitter describes the chemical substances that make it possible for messages to cross from the synapse of a neuron to the target receptor.

<h3>What are Neurotransmitters?</h3>

Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body.
Chemical synaptic transmission is primarily through the release of neurotransmitters from presynaptic neural cells to postsynaptic receptors.
There are a number of neurotransmitters used by the body for different functions, including acetylcholine, norepinephrine, glutamate, GABA, glycine, dopamine, and serotonin.
Glutamate is the principal excitatory neurotransmitter used in the brain.
GABA and Glycine serve as the major inhibitory neurotransmitters.
