RSSVector (biology)
Traditionally in medicine, a
vector is an organism that
does not cause disease
itself but which spreads
infection by conveying
pathogens from one host to
another. Species of
mosquito, for example, serve

Motor neuron
In vertebrates, motor
neurons (also called
motoneurons) are efferent
neurons that originate in
the spinal cord and synapse
with muscle fibers to
facilitate muscle
contraction and with muscle

Allele frequency
Allele frequency is a
measure of the relative
frequency of an allele on a
genetic locus in a
population. Usually it is
expressed as a proportion or
a percentage. In population
genetics, allele frequencies
