The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.

Answer:
An evolutionary lineage is a temporal series of organisms, populations, cells, or genes connected by a continuous line of descent from ancestor to descendant. Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.
Answer:
A
Explanation:
Agglutination would occur because a person with type B blood cannot receive AB blood because they have A antibodies.
The cell body must undergo Anterograde transport to reach the synaptic knobs.
The synaptic feature is to transmit nerve impulses between two nerve cell neurons or among a neuron and muscle cellular. Synapses connect one neuron to every other and are thus liable for the transmission of messages from the nerves to the mind and vice versa.
Synapses are a part of the circuit that connects sensory organs, like those who come across aches or touch, within the peripheral frightened gadget to the mind. Synapses connect neurons inside the mind to neurons inside the rest of the frame and from those neurons to the muscle tissues.
Synaptic transmission is the method at synapses by way of which a chemical sign is launched from one neuron and diffuses to other neurons or goal cells where it generates a sign which excites, inhibits, or modulates mobile hobby.
