Answer:
Gene: The hereditary material made up of alleles.
Alleles: The alternative forms of a gene.
Dominant: An allele or trait that masks the effect of recessive allele or trait.
Recessive: An allele or trait that gets suppressed by the dominant allele or trait.
genotype: The genome of a particular organism of the genes which make up an organism.
phenotype: The physical traits or characteristics of an organism.
test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.
law of independent assortment: Alleles of different genes get assorted independently into gametes.
law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.
product rule: Independent evens can be calculated by multiplying the independent probabilities.
Addition rule: The probability which shows that one event would occur in a mutually exclusive event.
co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.
incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
Explanation:
Answer:
The concept predates the term; Plato suggested applying the principles of selective breeding to humans around 400 BC. Early advocates of eugenics in the 19th century regarded it as a way of improving groups of people. In modern usage, the term eugenics has close ties to scientific racism and white supremacism.

Sympathetic nervous system under the Autonomic nervous system (ANS) is responsible for the physiological changes you experience when startled by a loud noise.
Autonomic nervous system (ANS) is part of the peripheral nervous system (PNS) and is responsible for control of vital functions.
ANS possesses three divisions, they are : Sympathetic nervous system (SYNS), parasympathetic nervous system and enteric plexus. Sympathetic nervous system is responsible for flight and fight responses.
SYNS also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.
The ganglions associated with SYNS mostly arise from the thoracic and lumbar regions of the spinal cord.
