Heredity is the passing of traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause some species to evolve through the natural selection of specific phenotype traits. The study of heredity in biology is called genetics, which includes the field of epigenetics.
In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype.
The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment. As a result, many aspects of an organism's phenotype are not inherited. For example, suntanned skin comes from the interaction between a person's phenotype and sunlight; thus, suntans are not passed on to people's children. However, some people tan more easily than others, due to differences in their genotype: a striking example is people with the inherited trait of albinism, who do not tan at all and are very sensitive to sunburn.
Hear my cries of anguish
I suffered a thousand deaths
but I live on in vain
Out of your mind I come
I am the avenger,
shapeless and faceless
immortal and everlasting harred
I can see all the rivers of flames
Lost in the Land of no return
Grant me the powers of light
reach out to the mirror
embraced by this cloudly nothingness
I can see the darker side
Shadowflame
Another sunrise swathes the earth in light
you feel the fright you know I'm near
beneath the cold of the frozen sun
